Lett. B Report-no: CMS-SUS-14-021, CERN-PH-EP-2015-307 \\ Results are presented from a search for supersymmetric particles in scenarios with a compressed mass spectrum. The data sample corresponds to 19.7 inverse femtobarns of proton-proton collisions recorded by the CMS experiment at sqrt(s)=8 TeV. The search targets top squark pair production in scenarios with mass differences Delta m = m(top squark) - m(neutralino) below the W-boson mass and with top-squark decays in the four-body mode (top squark to b l nu neutralino), where the neutralino is assumed to be the lightest supersymmetric particle (LSP). The signature includes a high transverse momentum (pt) jet associated with initial-state radiation, one or two low-pt leptons, and significant missing transverse energy. The event yields observed in data are consistent with the expected background contributions from standard model processes. Limits are set on the cross section for top squark pair production as a function of the top squark and LSP masses. Assuming a 100% branching fraction for the four-body decay mode, top-squark masses below 316 GeV are excluded for Delta m=25 GeV at 95% CL. The dilepton data are also interpreted under the assumption of chargino-neutralino production, with subsequent decays to sleptons or sneutrinos. Assuming a difference between the common lightest chargino/next lightest neutralino mass and the LSP mass of 20 GeV and a tau-enriched decay scenario, masses in the range m(chargino)<307 GeV are excluded at 95% CL. \\ ( http://arxiv.org/abs/1512.08002 , 496kb) ------------------------------------------------------------------------------ \\ arXiv:1512.08197 Date: Sun, 27 Dec 2015 10:29:46 GMT (72kb) Title: Study of $J/\psi\to p\bar{p}\phi$ at BESIII Authors: BESIII Collaboration: M.

The branching fraction of $J/\psi\to p\bar{p}\phi$ is measured to be $\mathcal{B}(J/\psi\to p\bar{p}\phi)=[5.23\pm0.06(\mbox{stat})\pm0.33(\mbox{syst})]\times10^{-5}$, which agrees well with a previously published measurement, but with a significantly improved precision. No evident enhancement near the $p\bar{p}$ mass threshold, denoted as $X(p\bar{p})$, is observed, and the upper limit on the branching fraction of $J/\psi\to X(p\bar{p})\phi\to p\bar{p}\phi$ is determined to be $\mathcal{B}(J/\psi\to X(p\bar{p})\phi\to p\bar{p}\phi)<2.1\times10^{-7}$ at the 90\% confidence level. \\ ( http://arxiv.org/abs/1512.08197 , 72kb) ------------------------------------------------------------------------------ \\ arXiv:1512.08202 Date: Sun, 27 Dec 2015 11:11:27 GMT (417kb,D) Title: A non-conventional neutrino beamline for the measurement of the electron neutrino cross section Authors: A.

In order to evade such limitation and reach the accuracy that is needed for precision oscillation physics ($\sim 1$%), substantial advances in flux measurement techniques are requested. We discuss here the possibility of instrumenting the decay tunnel to identify large-angle positrons and monitor $\nu_e$ production from $K^+ \rightarrow e^+ \nu_e \pi^0$ decays. This non conventional technique opens up opportunities to measure the $\nu_e$ CC cross section at the per cent level in the energy range of interest for DUNE/HK. We discuss the progress in the simulation of the facility (beamline and instrumentation) and the ongoing R&D. \\ ( http://arxiv.org/abs/1512.08202 , 417kb) ------------------------------------------------------------------------------ \\ arXiv:1512.08256 Date: Sun, 27 Dec 2015 18:18:34 GMT (1183kb,D) Title: Precision Measurements of Electroweak Parameters with Z Bosons at the Tevatron Authors: Arie Bodek Categories: hep-ex hep-ph Comments: For the CDF and D0 Collaborations, in Proceedings of the Third Annual Large Hadron Collider Physics Conference LHCP15, Aug. 31-Sept 5, 2015 Saint Petersburg, Russia. 13 pages, 6 figures \\ We report on the extraction of $\sin^2\theta^{\rm lept}_{\rm eff}(M_Z)$ and an indirect measurement of the mass of the W boson from the forward-backward asymmetry of dilepton events in the $Z$ boson mass region at the Tevatron. The data samples of $e^+e^-$ and $\mu^+\mu^-$ events collected by the CDF detector correspond to the full 9.4 fb$^{-1}$ run II sample and yield an effective electroweak mixing angle $\sin^2\theta^{\rm lept}_{\rm eff}(M_Z) = 0.23222 \pm 0.00046$. The corresponding result reported by the D0 collaboration with the full 9.4 fb$^{-1}$ $e^+e-$ sample is $\sin^2\theta^{\rm lept}_{\rm eff}(M_Z) = 0.23146 \pm 0.00047$. The CDF collaboration also extracts the on-shell electroweak mixing angle $ \sin^2 \theta_W = 0.22401 \pm 0.00044$ which corresponds to an indirect measurement of the W boson mass $M_W ({\rm indirect}) = 80.327 \pm 0.023 \;{\rm GeV}$.

High Energy Phys Report-no: CMS-HIG-14-028, CERN-PH-EP-2015-285 \\ Differential and integrated fiducial cross sections for the production of four leptons via the H to 4l decays (l = e, mu) are measured in pp collisions at sqrt(s) = 7 and 8 TeV. Measurements are performed with data corresponding to integrated luminosities of 5.1 inverse-femtobarns at 7 TeV, and 19.7 inverse-femtobarns at 8 TeV, collected with the CMS experiment at the LHC. Differential cross sections are determined as functions of the transverse momentum and rapidity of the four-lepton system, accompanying jet multiplicity, transverse momentum of the leading jet, and difference in rapidity between the Higgs boson candidate and the leading jet. A measurement of the Z to 4l cross section, and its ratio to the H to 4l cross section is also performed. All cross sections are measured within a fiducial phase space defined by the requirements on lepton kinematics and event topology. The integrated H to 4l fiducial cross section is measured to be 0.56 +0.67-0.44 (stat) +0.21-0.06 (syst) fb at 7 TeV, and 1.11 +0.41-0.35 (stat) +0.14-0.10 (syst) fb at 8 TeV. The measurements are found to be compatible with theoretical calculations based on the standard model. \\ ( http://arxiv.org/abs/1512.08377 , 351kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1512.05779 (*cross-listing*) Date: Thu, 17 Dec 2015 20:58:02 GMT (61kb) Date (revised v2): Fri, 25 Dec 2015 06:59:57 GMT (371kb) Title: A 750 GeV Dark Pion: Cousin of a Dark G-parity-odd WIMP Authors: Yang Bai, Joshua Berger and Ran Lu Categories: hep-ph hep-ex Comments: 14 pages, 4 figures \\ We point out a potential common origin of the recently observed 750 GeV diphoton resonance and a Weakly Interacting Massive Particle (WIMP) candidate. In a dark QCD sector with an unbroken dark G-parity, the diphoton resonance could be a dark G-even pion, while the WIMP could be the lightest dark G-odd pion. Both particles are Standard Model gauge singlets and have the same decay constant. For the dark pion decay constant of around 500 GeV, both the diphoton excess at the LHC and the dark matter thermal abundance can be accommodated in our model. Our model predicts additional dark G-even and dark G-odd color-octet pions within reach of the 13 TeV LHC runs. For the 5 + 5bar model, compatible with the Grand Unified Theories, the WIMP mass is predicted to be within (613, 750) GeV. \\ ( http://arxiv.org/abs/1512.05779 , 371kb) ------------------------------------------------------------------------------ \\ arXiv:1512.07645 (*cross-listing*) Date: Wed, 23 Dec 2015 21:44:45 GMT (242kb,D) Title: Di-photon Excess Explained by a Resonant Sneutrino in R-parity Violating Supersymmetry Authors: B.

The stau mass is somewhere between half the resonant sneutrino mass and half the sneutrino mass plus 14 GeV. The scenario predicts further signal channels at an invariant mass of 750 GeV: the most promising being into di-jets. \\ ( http://arxiv.org/abs/1512.07645 , 242kb) ------------------------------------------------------------------------------ \\ arXiv:1512.07699 (*cross-listing*) Date: Thu, 24 Dec 2015 02:59:29 GMT (104kb,D) Title: Measurement of Neutrino Flux from Neutrino-Electron Elastic Scattering Authors: MINERvA Collaboration: J.

Consequently a measurement of this process in an accelerator-based $\nu_\mu$ beam can improve the knowledge of the absolute neutrino flux impinging upon the detector; typically this knowledge is limited to $\sim$ 10% due to uncertainties in hadron production and focusing. We have isolated a sample of 135 $\pm$ 17 neutrino-electron elastic scattering candidates in the segmented scintillator detector of MINERvA, after subtracting backgrounds and correcting for efficiency. We show how this sample can be used to reduce the total uncertainty on the NuMI $\nu_\mu$ flux from 9% to 6%. Our measurement provides a flux constraint that is useful to other experiments using the NuMI beam, and this technique is applicable to future neutrino beams operating at multi-GeV energies. \\ ( http://arxiv.org/abs/1512.07699 , 104kb) ------------------------------------------------------------------------------ \\ arXiv:1512.07789 (*cross-listing*) Date: Thu, 24 Dec 2015 11:18:38 GMT (57kb) Title: The 750 GeV Diphoton excess in a $U(1)$ hidden symmetry model Authors: Kasinath Das and Santosh Kumar Rai Categories: hep-ph hep-ex Comments: 5 pages, 2 eps figures Report-no: HRI-RECAPP-2015-021 \\ Recent results from the experimental collaborations at LHC give hints of a resonance in the diphoton channel at an invariant mass of 750 GeV. We show that such a scalar resonance would be possible in an $U(1)$ extension of the SM where the extended symmetry is hidden and yet to be discovered. We explore the possibilities of accommodating this excess by introducing a minimal extension to the matter content and highlight the parameter space that can accommodate the observed diphoton resonance in the model. The model also predicts new interesting signals that may be observed at the current LHC run. \\ ( http://arxiv.org/abs/1512.07789 , 57kb) ------------------------------------------------------------------------------ \\ arXiv:1512.07836 (*cross-listing*) Date: Mon, 14 Dec 2015 11:18:36 GMT (35kb,D) Title: General formulation of process noise matrix for track fitting with Kalman filter Authors: Kolahal Bhattacharya, Sudeshna Banerjee, Naba K Mondal Categories: physics.ins-det hep-ex Comments: Total 18 pages, 2 figures \\ In the context of track fitting problems by a Kalman filter, the general functional forms of the elements of the random noise matrix are derived for tracking through thick layers of materials and magnetic fields.

Hall, Keisuke Harigaya, and Yasunori Nomura Categories: hep-ph hep-ex Comments: 7 pages, 3 figures \\ A recent signal of 750 GeV diphotons at the LHC can be explained within the framework of supersymmetric unification by the introduction of vector quarks and leptons with Yukawa couplings to a singlet S that describes the 750 GeV resonance. We study the most general set of theories that allow successful perturbative gauge coupling unification, and find that these Yukawa couplings are severely constrained by renormalization group behavior: they are independent of ultraviolet physics and flow to values at the TeV scale that we calculate precisely. As a consequence the vector quarks and leptons must be light; typically in the region of 375 GeV to 700 GeV, and in certain cases up to 1 TeV. The 750 GeV resonance may have a width less than the experimental resolution; alternatively, with the mass splitting between scalar and pseudoscalar components of S arising from one-loop diagrams involving vector fermions, we compute an apparent width of 10s of GeV. \\ ( http://arxiv.org/abs/1512.07904 , 177kb) ------------------------------------------------------------------------------ \\ arXiv:1512.07926 (*cross-listing*) Date: Thu, 24 Dec 2015 22:29:07 GMT (1092kb,D) Title: Gaseous time projection chambers for rare event detection: Results from the T-REX project.

Mirallas, E. Ruiz, L. Segu\'i, A. Tom\'as Categories: physics.ins-det hep-ex Comments: prepared for submission to JCAP \\ As part of the T-REX project, a number of R&D and prototyping activities have been carried out during the last years to explore the applicability of gaseous Micromegas-read TPCs in rare event searches like double beta decay (DBD), axion research and low-mass WIMP searches. In both this and its companion paper, we compile the main results of the project and give an outlook of application prospects for this detection technique. While in the companion paper we focus on axions and WIMPs, in this paper we focus on the results regarding the measurement of the DBD of $^{136}$Xe in a high pressure Xe (HPXe) TPC. Particularly relevant are the results obtained in Xe + TMA mixtures with microbulk Micromegas, showing very promising results in terms of gain, stability of operation, and energy resolution at pressures up to 10 bar. TMA at levels of $\sim$1\% reduces electron diffusion by a factor of 10 with respect to pure Xe, improving the quality of the topological pattern, with a positive impact on the discrimination capability. Operation with a medium size prototype (30 cm diameter and 38 cm drift) of 1 kg of Xe at 10 bar in the fiducial volumen has allowed to test the detection concept in realistic experimental conditions. Microbulk Micromegas are able to image the DBD ionization signature with high quality while, at the same time, measuring its energy deposition with a resolution of at least $\sim$3% FWHM @ Q$_{\beta\beta}$, and probably down to $\sim$1% FWHM. In addition, first results on the topological signature information show promising background discrimination capabilities out of reach of other experimental implementations. Moreover, microbulk Micromegas have very low levels of intrinsic radioactivity, and offer cost-effective scaling-up options. All these results demonstrate that Micromegas-read HPXe TPC is a very competitive technique for the next generation DBD experiments. \\ ( http://arxiv.org/abs/1512.07926 , 1092kb) ------------------------------------------------------------------------------ \\ arXiv:1512.07992 (*cross-listing*) Date: Fri, 25 Dec 2015 12:50:32 GMT (1308kb) Title: Dark Matter Theories in the Light of Diphoton Excess Authors: Huayong Han, Shaoming Wang and Sibo Zheng Categories: hep-ph hep-ex Comments: 7 pages, 4 figures \\ A new type of dark matter (DM) theories are proposed in the light of the standard model (SM) singlet scalar $\phi$ which is responsible for the diphoton excess at the LHC Run 2.

In a homogeneous plasma, the electrons are radially sucked-in from all the different radii. The electrons collapsing from different radii do not simultaneously compress on-axis driving weak fields. A hollow-channel allows electrons from its channel-radius to collapse simultaneously exciting coherent fields. We analyze the optimal channel radius. Additionally, the low ion density in the hollow allows a larger region with focusing phase which we show is linearly focusing. We have shown the formation of an ion-wake channel behind a blow-out electron bubble-wake. Here we explore positron acceleration in the over-dense regime comparing an optimal hollow-plasma channel to the ion-wake channel. The condition for optimal hollow-channel radius is also compared. We also address the effects of a non-ideal ion-wake channel on positron-beam excited fields. \\ ( http://arxiv.org/abs/1512.08013 , 5542kb) ------------------------------------------------------------------------------ \\ arXiv:1512.08046 (*cross-listing*) Date: Fri, 25 Dec 2015 22:59:54 GMT (68kb) Title: Heavy-ion hot hadron matter freezes out at T=170-320 MeV? Authors: Volodymyr Vovchenko, Horst St\"ocker Categories: hep-ph hep-ex hep-lat nucl-ex nucl-th Comments: 5 pages, 2 figures \\ The conventional hadron-resonance gas (HRG) model with the Particle Data Group (PDG) hadron input and the mass dependent eigenvolume corrections is employed to fit the ALICE hadron mid-rapidity yield data on the most central Pb+Pb collisions. For the case of the point-like hadrons a well-known fit result of $T \sim 155$ MeV is reproduced. However, when we apply the eigenvolume corrections with the mass-proportional eigenvolume $v_i \sim m_i$, fixed to the realistic proton hard-core radius $r_p \simeq 0.4-0.5$ fm, we observe a second minimum in the temperature dependence of the $\chi^2$, located at the significantly higher temperatures. For instance, at $r_p = 0.5$ fm the fit quality is better than in the point-particle HRG case in a very wide temperature range of $170-320$ MeV, with the global minimum located at $T \simeq 275$ MeV and $\chi^2/N_{\rm dof} \simeq 1.5$. These results show that one cannot extract the chemical freeze-out temperature with high reliability from the LHC hadron yield data. Implications for the ongoing ALICE heavy-ion run at 5.02 TeV are discussed. \\ ( http://arxiv.org/abs/1512.08046 , 68kb) ------------------------------------------------------------------------------ \\ arXiv:1512.08076 (*cross-listing*) Date: Sat, 26 Dec 2015 05:44:12 GMT (432kb) Title: Basic oscillation measurables in the neutrino pair beam Authors: T.

When the resonance particle is identified as the pseudo-scalar mediator, via which the standard model sector would interact with the dark matter sector, the data from collider physics would provide profound implications to dark matter phenomenology. In this paper, we first identify the preferred parameter space of the suggested portal model from the results of the LHC run with $\sqrt{s}=13$ TeV, and then we examine the dark matter signature taking into account the data from cosmic-ray experiments including Fermi-LAT dwarf galaxy $\gamma$-ray search, HESS $\gamma$-line search, and future CTA diffuse $\gamma$-ray and $\gamma$-line searches. \\ ( http://arxiv.org/abs/1512.08117 , 1186kb) ------------------------------------------------------------------------------ \\ arXiv:1512.08221 (*cross-listing*) Date: Sun, 27 Dec 2015 13:55:02 GMT (1423kb,D) Title: Glue to light signal of a new particle Authors: Dongjin Chway, Radovan Derm\'i\v{s}ek, Tae Hyun Jung, Hyung Do Kim Categories: hep-ph hep-ex Comments: 4 pages, 5 figures \\ Any new particle charged under $SU(3)_C$ and carrying electric charge will leave an imprint in the di-photon invariant mass spectrum as it can mediate $gg \to \gamma \gamma$ process through loops. The combination of properties of loop functions and gluon pdfs results in a peak-like feature in the di-photon invariant mass around twice the mass of a given particle. Using recent ATLAS analysis, we set upper limits on the combined $SU(3)_C$ and electric charge of new particles and indicate future prospects. We briefly discuss the possibility that the excess of events in the di-photon invariant mass spectrum around 750 GeV originates from loops of a particle with mass around 375 GeV. \\ ( http://arxiv.org/abs/1512.08221 , 1423kb) ------------------------------------------------------------------------------ \\ arXiv:1512.08290 (*cross-listing*) Date: Sun, 27 Dec 2015 23:42:18 GMT (184kb,D) Title: High order QCD predictions for inclusive production of $W$ bosons in $pp$ collisions at $\sqrt{s}$$=13$ TeV Authors: Hasan Ogul, Kamuran Dilsiz, Emrah Tiras, Ping Tan, Yasar Onel and Jane Nachtman Categories: hep-ph hep-ex \\ Predictions of fiducial cross sections, differential cross sections and lepton charge asymmetry are presented for the production of $W^{\pm}$ bosons with leptonic decay up to next-to-next-to-leading order (NNLO) in perturbative QCD. Differential cross sections of $W^{\pm}$ bosons and W boson lepton charge asymmetry are computed as a function of lepton pseudorapidity for a defined fiducial region in $pp$ collisions at $\sqrt{s}=13$ TeV. Numerical results of fiducial $W^{\pm}$ cross section predictions are presented with the latest modern PDF models at next-to-leading order (NLO) and NNLO. It is found that the NNLO corrections increase the NLO CT14 and NNPDF 3.0 predictions by approximately 4$\%$ while it increases MMHT 2014 predictions at NLO by approximately 6$\%$. In addition, the NNLO QCD corrections reduce the scale variation uncertainty by a factor of 3.5. \\ ( http://arxiv.org/abs/1512.08290 , 184kb) ------------------------------------------------------------------------------ \\ arXiv:1512.08373 (*cross-listing*) Date: Mon, 28 Dec 2015 10:58:31 GMT (264kb,D) Title: New Avenues to Heavy Right-handed Neutrinos with Pair Production at Hadronic Colliders Authors: Zhaofeng Kang, P. Ko, Jinmian Li Categories: hep-ph hep-ex Comments: 34 pages, 8 figures \\ In many models incorporating the type-I seesaw mechanism, the right-handed neutrino ($N$) couples to heavy vector/scalar bosons and thereby has resonant pair production. It barely receives attention thus far, however, it may provide the best avenue to probe TeV scale $N$ without requiring anomalously large mixing between $N$ and the active neutrino $\nu_L$. In this paper we explore the discovery prospects of (mainly heavy) $N$ pair production at the 14 TeV LHC and future 100 TeV $pp$ collider, based on the three signatures: 1) trilepton from $ N(\to \ell W_\ell)N(\to \ell W_h)$ with $W_{\ell/h}$ the leptonically/hadronically decaying $W$; 2) boosted di-Higgs boson plus MET from $ N(\to \nu_L h)N(\to \nu_L h)$; 3) a single boosted Higgs with leptons and MET from $N(\to \ell W_\ell)N(\to \nu_L h)$. At the 100 TeV collider, we also consider the situation when the Higgs boson is over boosted thus losing its jet substructure. Interpreting our tentative results in the benchmark model, the local $B-L$ model, we find that the (multi-) TeV scale $N$ can be probed at the (100) 14 TeV colliders. \\ ( http://arxiv.org/abs/1512.08373 , 264kb) ------------------------------------------------------------------------------ \\ arXiv:1512.08378 (*cross-listing*) Date: Mon, 28 Dec 2015 11:22:07 GMT (304kb,D) Title: Broad Diphotons from Narrow States Authors: Haipeng An, Clifford Cheung, Yue Zhang Categories: hep-ph hep-ex Comments: 7 pages, 6 figures Report-no: CALT-TH-2015-065 \\ ATLAS and CMS have each reported a modest diphoton excess consistent with the decay of a broad resonance at ~ 750 GeV. We show how this signal can arise in a weakly coupled theory comprised solely of narrow width particles. In particular, if the decaying particle is produced off-shell, then the associated diphoton resonance will have a broad, adjustable width. We present simplified models which explain the diphoton excess through the three-body decay of a scalar or fermion. Our minimal ultraviolet completion is a weakly coupled and renormalizable theory of a singlet scalar plus a heavy vector-like quark and lepton. The smoking gun of this mechanism is an asymmetric diphoton peak recoiling against missing transverse energy, jets, or leptons. \\ ( http://arxiv.org/abs/1512.08378 , 304kb) ------------------------------------------------------------------------------ \\ arXiv:1512.08434 (*cross-listing*) Date: Mon, 28 Dec 2015 15:36:47 GMT (15kb) Title: Interpreting 750 GeV Diphoton Resonance in the NMSSM with Vector-like Particles Authors: Fei Wang, Wenyu Wang, Lei Wu, Jin Min Yang and Mengchao Zhang Categories: hep-ph hep-ex Comments: 13 pages \\ In this work, we explain the recent observed 750 GeV diphoton resonance in the Next-to-Minimal Supersymmetric Standard Model (NMSSM) by introducing vector-like chiral superfields. Such an extension is well motivated from the top-down view since some grand unified theories usually predict the existence of singlet scalars and vector-like particles at weak scale. In our model, the 750 GeV resonance can be interpreted as two nearly degenerate singlet-like Higgs bosons ($m_{h_2}\approx m_{a_1} \approx 750$ GeV). The decays of $h_2/a_1 \to \gamma\gamma$ are dominated by the vector-like squarks with large mixing, which can also enhance the production cross section of $gg \to h_2/a_1$. Under the constraints from the Higgs data and dark matter detection, we scan the parameter space and find that such a model can successfully accounts for the diphoton excess. \\ ( http://arxiv.org/abs/1512.08434 , 15kb) ------------------------------------------------------------------------------ \\ arXiv:1512.08441 (*cross-listing*) Date: Mon, 28 Dec 2015 16:16:20 GMT (756kb,D) Title: The Diphoton Excess, Low Energy Theorem and the 331 Model Authors: Qing-Hong Cao, Yandong Liu, Ke-Pan Xie, Bin Yan, Dong-Ming Zhang Categories: hep-ph hep-ex \\ We interpret the diphoton anomaly as a heavy scalar $H_3$ in the so-called 331 model. The scalar is responsible for breaking the $SU(3)_C\otimes SU(3)_L\otimes U(1)_X$ gauge symmetry down to the standard model electroweak gauge group. It mainly couples to the standard model gluons and photons through quantum loops involving heavy quarks and leptons. Those quarks and leptons, in together with the SM quarks and leptons, form the fundamental representation of the 331 model. We use low energy theorem to calculate effective coupling of $H_3gg$, $H_3\gamma\gamma$, $H_3ZZ$, $H_3WW$ and $H_3Z\gamma$. The analytical results can be applied to new physics models satisfying the low energy theorem. We show that the heavy quark and lepton contribution cannot produce enough diphoton pairs. It is crucial to include the contribution of charged scalars to explain the diphoton excess. The extra neutral $Z^\prime$ boson could also explain the 2 TeV diboson excess observed at the LHC Run-I. \\ ( http://arxiv.org/abs/1512.08441 , 756kb) ------------------------------------------------------------------------------ \\ arXiv:1512.08478 (*cross-listing*) Date: Mon, 28 Dec 2015 18:35:03 GMT (392kb,D) Title: Diphoton excess at 750 GeV: gluon-gluon fusion or quark-antiquark annihilation? Authors: Jun Gao, Hao Zhang, Hua Xing Zhu Categories: hep-ph hep-ex Comments: 20 pages, 7 figures Report-no: MIT-CTP-4757 \\ Recently, ATLAS and CMS collaboration reported an excess in the diphoton events, which can be explained by a new resonance with mass around 750 GeV. In this work, we explored the possibility of identifying if the hypothetical new resonance is produced through gluon-gluon fusion or quark-antiquark annihilation, or tagging the beam. Three different observables for beam tagging, namely the rapidity and transverse momentum distribution of the diphoton, and one tagged bottom-jet cross section, are proposed. Combining the information gained from these observables, a clear distinction of the production mechanism for the diphoton resonance is promising. \\ ( http://arxiv.org/abs/1512.08478 , 392kb) ------------------------------------------------------------------------------ \\ arXiv:1512.08500 (*cross-listing*) Date: Mon, 28 Dec 2015 20:27:26 GMT (483kb,D) Title: Indirect Constraints on the Scalar Di-Photon Resonance at the LHC Authors: Florian Goertz, Jernej F. Kamenik, Andrey Katz, Marco Nardecchia Categories: hep-ph hep-ex Comments: 29 pages, 3 figures \\ Motivated by the tantalizing excesses recently reported in the di-photon in- variant mass spectrum at the LHC, we scrutinize some implications of scalar di-photon resonances in high energy proton-proton collisions. In particular, indications of a large width impose several challenges on model building. We show how calculability and uni- tarity considerations severely limit possible perturbative realizations of such a signal and propose a simple criterion that can be adapted to any renormalizable model. Furthermore, we discuss correlations between a di-photon excess and precision observables, including the anomalous magnetic and electric dipole moments of quarks and leptons, neutral me- son oscillations and radiative flavor changing neutral current mediated decays of heavy leptons and hadrons. We find that existing searches and measurements significantly con- strain the possibilities for a scalar resonance decaying into final states involving Standard Model fermions. We propose future search strategies which could elucidate some remaining currently unconstrained decay channels and discuss possible correlations between the di- photon excess and several recently reported flavor anomalies, showing that the latter can be addressed in a new incarnation of a gauged U(1) model, with the di-photon resonance being the physical remnant of the U(1)-breaking field. \\ ( http://arxiv.org/abs/1512.08500 , 483kb) ------------------------------------------------------------------------------ \\ arXiv:1512.08507 (*cross-listing*) Date: Mon, 28 Dec 2015 20:46:53 GMT (507kb,D) Title: Quark Seesaw Vectorlike Fermions and Diphoton Excess Authors: P.

The gauge singlet real scalar field responsible for the mass of the vectorlike fermions has the right production cross section and diphoton branching ratio to be identifiable with the reported excess at around 750 GeV diphoton invariant mass. Various ways to test this hypothesis as more data accumulates at the LHC are proposed. In particular, we find that for our interpretation to work, there is an upper limit on the right-handed scale $v_R$, which depends on the Yukawa coupling of singlet Higgs field to the vectorlike fermions. \\ ( http://arxiv.org/abs/1512.08507 , 507kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1507.05200 (*cross-listing*) replaced with revised version Thu, 24 Dec 2015 06:27:20 GMT (50kb) Title: $\bar{D}\Sigma^*_c$ and $\bar{D}^*\Sigma_c$ interactions and the LHCb hidden-charmed pentaquarks Authors: Jun He Categories: hep-ph hep-ex hep-lat nucl-ex nucl-th Comments: 5 pages, 3 figures, accepted by Phys.
