This produces a 'split' spectrum, where the strong sector resonances have masses greater than 10 TeV and are separated from the pseudo Nambu-Goldstone bosons, which remain near the electroweak scale. Even though a tuning of order 10^{-4} is required to obtain the observed Higgs boson mass, the big hierarchy problem remains mostly solved. Intriguingly, models with a fully-composite right-handed top quark also exhibit improved gauge coupling unification. By restricting ourselves to models which preserve these features we find that the symmetry breaking scale cannot be arbitrarily raised, leading to an upper bound f < 100 TeV. This implies that the resonances may be accessible at future colliders, or indirectly via rare-decay experiments. Dark matter is identified with a pseudo Nambu-Goldstone boson, and we show that the smallest coset space containing a stable, scalar singlet and an unbroken SU(5) symmetry is SU(7) / SU(6) x U(1). The colour-triplet pseudo Nambu-Goldstone boson also contained in this coset space is metastable due to a residual symmetry. It can decay via a displaced vertex when produced at colliders, leading to a distinctive signal of unnaturalness. \\ ( http://arxiv.org/abs/1409.7391 , 905kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7392 Date: Thu, 25 Sep 2014 20:00:04 GMT (2300kb,D) Title: Soft Collinear Effective Theory for Heavy WIMP Annihilation Authors: Martin Bauer, Timothy Cohen, Richard J. Hill, and Mikhail P. Solon Categories: hep-ph Comments: 49 pages, 12 figures Report-no: EFI 14-32, FERMILAB-PUB-14-359-PPD, SLAC-PUB-16094 \\ In a large class of models for Weakly Interacting Massive Particles (WIMPs), the WIMP mass $M$ lies far above the weak scale $m_W$. This work identifies universal Sudakov-type logarithms $\sim \alpha \log^2 (2\,M/m_W)$ that spoil the naive convergence of perturbation theory for annihilation processes. An effective field theory (EFT) framework is presented, allowing the systematic resummation of these logarithms. Another impact of the large separation of scales is that a long-distance wave-function distortion from electroweak boson exchange leads to observable modifications of the cross section. Careful accounting of momentum regions in the EFT allows the rigorously disentanglement of this so-called Sommerfeld enhancement from the short distance hard annihilation process. The WIMP is modeled as a heavy-particle field, while the light, energetic, final-state electroweak gauge bosons are treated as soft and collinear fields. Hard matching coefficients are computed at renormalization scale $\mu \sim 2\,M$, then evolved down to $\mu \sim m_W$, where electroweak symmetry breaking is incorporated and the matching onto the relevant quantum mechanical Hamiltonian is performed. The example of an $SU(2)_W$ triplet scalar dark matter candidate annihilating to line photons is used for concreteness, allowing the numerical exploration of the impact of next-to-leading order corrections and log resummation. For $M \simeq 3$ TeV, the resummed Sommerfeld enhanced cross section is reduced by a factor of $\sim 3$ with respect to the tree-level fixed order result. \\ ( http://arxiv.org/abs/1409.7392 , 2300kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7412 Date: Thu, 25 Sep 2014 20:27:07 GMT (1062kb,D) Title: Electron Structure: Shape, Size and GPDs in QED Authors: Gerald A. Miller Categories: hep-ph nucl-ex nucl-th Comments: 20 pages, 10 figures Report-no: NT@UW-14-20 \\ The shape of the electron is studied using lowest-order perturbation theory. Quantities used to probe the structure of the proton: form factors, generalized parton distributions, transverse densities, Wigner distributions and the angular momentum content are computed for the electron-photon component of the electron wave function. The influence of longitudinally polarized photons, demanded by the need for infrared regularization via a non-zero photon mass, is included. The appropriate value of the photon mass depends on experimental conditions, and consequently the size of the electron (as defined by the slope of its Dirac form factor) bound in a hydrogen atom is found to be about four times larger than when the electron is free. The shape of the electron, as determined from the transverse density and generalized parton distributions is shown to not be round, and the free electron is shown to be far less round than the bound electron. An electron distribution function (analogous to the quark distribution function) is defined, and that of the bound electron is shown to be suppressed compared to that of the free electron. If the relative transverse momentum of the virtual electron and photon is large compared with the electron mass, the virtual electron and photon each carry nearly the total angular momentum of the physical electron (1/2), with the orbital angular momentum being nearly (-1/2). Including the non-zero photon mass leads to the suppression of end-point contributions to form factors. Implications for proton structure and color transparency are discussed. \\ ( http://arxiv.org/abs/1409.7412 , 1062kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7438 Date: Thu, 25 Sep 2014 23:07:17 GMT (78kb,D) Title: QCD chiral symmetry restoration with a large number of quarks in a model with a confining propagator and dynamically massive gluons Authors: R. M. Capdevilla, A. Doff and A. A. Natale Categories: hep-ph Comments: 11 pages, 4 figures \\ Considering a QCD chiral symmetry breaking model where the gap equation contains an effective confining propagator and a dressed gluon propagator with a dynamically generated mass, we verify that the chiral symmetry is restored for a large number of quarks $n_{f}\approx 11-13$. We discuss the uncertainty in the results, that is related to the determination of the string tension ($K_{F}$), appearing in the confining propagator, and the effective gluon mass ($m_{g}$) at large $n_{f}$. \\ ( http://arxiv.org/abs/1409.7438 , 78kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7462 Date: Fri, 26 Sep 2014 02:29:02 GMT (518kb) Title: The Early Universe with High-Scale Supersymmetry Authors: Sibo Zheng Categories: hep-ph astro-ph.CO hep-th Comments: 17 pp \\ The large tensor-to-scalar ratio reported by BICEP2 collaboration may lead to distinctive phenomenology of high-energy scale. Assuming the same origin of SUSY breaking between inflation and MSSM, we show model independent features in such high-scale SUSY. The simplest hybrid inflation, together with a new linear term for inflaton field which is induced by large gravitino mass, is excluded by BICEP2 data. For superpartner masses far above electroweak scale we estimate the reheating temperature $T_R$ after inflation. We find that $T_R$ might be beneath the value required by thermal leptogenesis if inflaton decays to its products perturbatively, but above it if non-perturbatively instead. Due to kinematically blocking effect the gravitino overproduction can be also evaded in high-scale SUSY. \\ ( http://arxiv.org/abs/1409.7462 , 518kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7557 Date: Fri, 26 Sep 2014 12:46:07 GMT (199kb,D) Title: From Old Symmetries to New Symmetries: Quarks, Leptons and B-L Authors: Rabindra N. Mohapatra Categories: hep-ph Comments: 17 pages; 5 figures; Invited article for "Fifty years of Quarks" ed. by H. Fritzsch, to be published by World Scientific \\ The Baryon-Lepton difference ($B-L$) is increasingly emerging as a possible new symmetry of the weak interactions of quarks and leptons as a way to understand the small neutrino masses. There is the possibility that current and future searches at colliders and in low energy rare processes may provide evidence for this symmetry. This paper provides a brief overview of the early developments that led to B-L as a possible symmetry beyond the standard model, and also discusses some recent developments. \\ ( http://arxiv.org/abs/1409.7557 , 199kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7571 Date: Fri, 26 Sep 2014 13:51:55 GMT (372kb,D) Title: AdS/CFT for the early stages of heavy ion collisions Authors: Romuald A.

In particular, we discuss the prediction of the Higgs mass according to the formalism and point out that it is ~170 GeV, in clear disagreement with experiment. To remedy this problem, we extend the formalism to the superalgebra su(2/2), which extends the SM to the left-right symmetric model (LRSM) and accommodates a ~126 GeV Higgs. Both the SM in the su(2/1) case and the LRSM in the su(2/2) case are argued to emerge at ~4 TeV from an underlying theory in which the spacetime geometry is modified by the addition of a discrete extra dimension. The formulation of the exterior derivative in this model space suggests a deep connection between the modified geometry, which can be described in the language of non-commutative geometry (NCG), and the spontaneous breaking of the gauge symmetries. The implication is that spontaneous symmetry breaking could actually be geometric/quantum gravitational in nature. The non-decoupling phenomenon seen in the Higgs sector can then be reinterpreted in a new light as due to the mixing of low energy (SM) physics and high energy physics associated with quantum gravity, such as string theory. The phenomenology of a TeV scale LRSM is also discussed, and we argue that some exciting discoveries may await us at the LHC, and other near-future experiments. \\ ( http://arxiv.org/abs/1409.7574 , 1670kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7577 Date: Fri, 26 Sep 2014 14:04:06 GMT (501kb) Title: Radiative $\Omega_{Q}^{*}\rightarrow\Omega_{Q}\gamma$ and $\Xi_{Q}^{*}\rightarrow\Xi^{\prime}_{Q}\gamma$ transitions in light cone QCD Authors: T.

Sundu Categories: hep-ph Comments: 17 Pages, 12 Figures and 4 Tables \\ We calculate the magnetic dipole and electric quadrupole moments associated with the radiative $\Omega_{Q}^{*}\rightarrow\Omega_{Q}\gamma$ and $\Xi_{Q}^{*}\rightarrow\Xi^{\prime}_{Q}\gamma$ transitions with $Q=b$ or $c$ in the framework of light cone QCD sum rules. It is found that the corresponding quadrupole moments are negligibly small while the magnetic dipole moments are considerably large. A comparison of the results on the considered multipole moments as well as corresponding decay widths with the predictions of the vector dominance model is performed. \\ ( http://arxiv.org/abs/1409.7577 , 501kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7596 Date: Fri, 26 Sep 2014 15:02:35 GMT (150kb) Title: $H^\pm\to cb$ in models with two or more Higgs doublets Authors: A.G. Akeroyd (U. of Southampton, UK), S. Moretti (U. of Southampton, UK) and J. Hernandez-Sanchez (BUAP, Mexico) Categories: hep-ph Comments: 5 pages, 2 figures, proceedings of the workshop `Prospects for Charged Higgs Discovery at Colliders - CHARGED 2014', 16-18 September 2014, Uppsala University, Sweden \\ Searches for light $H^\pm$s via $t\to H^\pm b$ are being carried out at the LHC. Herein, it is normally assumed that the dominant decay channels are $H^\pm\to \tau\nu$ and $H^\pm\to cs$ and separate data analyses are performed with comparable sensitivity to the underlying model assumptions. However, the $H^\pm\to cb$ decay rate can be as large as $80\%$ in models with two or more Higgs doublets with natural flavour conservation, while satisfying the constraint from $b\to s\gamma$ for $m_{H^\pm}< m_t$. Despite the current search strategy for $H^\pm\to cs$ is also sensitive to $H^\pm\to cb$, a significant gain in sensitivity could be obtained by tagging the $b$ quark from the decay $H^\pm\to cb$. \\ ( http://arxiv.org/abs/1409.7596 , 150kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7605 Date: Fri, 26 Sep 2014 15:42:13 GMT (32kb) Title: On the consistent use of Constructed Observables Authors: Michael Trott Categories: hep-ph Comments: 21pp, 1 fig Report-no: CERN-PH-TH/2014-187 \\ We define "constructed observables" as relating experimental measurements to terms in a Lagrangian while simultaneously making assumptions about possible deviations from the Standard Model (SM), in other Lagrangian terms. Ensuring that the SM effective field theory (EFT) is constrained correctly when using constructed observables requires that their defining conditions are imposed on the EFT in a manner that is consistent with the equations of motion. Failing to do so can result in a "functionally redundant" operator basis and the wrong expectation as to how experimental quantities are related in the EFT. We illustrate the issues involved considering the $\rm S$ parameter and the off shell triple gauge coupling (TGC) verticies. We show that the relationships between $h \rightarrow V \bar{f} \, f$ decay and the off shell TGC verticies are subject to these subtleties, and how the connections between these observables vanish in the limit of strong bounds due to LEP. The challenge of using constructed observables to consistently constrain the Standard Model EFT is only expected to grow with future LHC data, as more complex processes are studied. \\ ( http://arxiv.org/abs/1409.7605 , 32kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7607 Date: Fri, 26 Sep 2014 15:46:01 GMT (559kb) Title: Single Top Production as a Probe of Heavy Resonances Authors: Elizabeth Drueke, Joseph Nutter, Reinhard Schwienhorst, Natascia Vignaroli, Devin G.

D Report-no: UTTG-21-14 \\ The single top quark final state provides sensitivity to new heavy resonances produced in proton-proton collisions at the Large Hadron Collider. Particularly, the single top plus quark final state appears in models with heavy charged bosons or scalars, or in models with flavor-changing neutral currents involving the top quark. The cross sections and final state kinematics distinguish such models from each other and from standard model backgrounds. Several models of resonances decaying to a single top quark final state are presented and their phenomenology is discussed. \\ ( http://arxiv.org/abs/1409.7607 , 559kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7684 Date: Fri, 26 Sep 2014 19:48:45 GMT (32kb,D) Title: Light-front holography in $B$ physics Authors: Mohammad Ahmady, S\'ebastien Lord, Ruben Sandapen Categories: hep-ph Comments: 6 pages, 4 figures.

While the canonical possibility is a strict cosmological constant, or rigid vacuum energy density $\rho_{\Lambda}=$const., the exceeding simplicity of this possibility lies also at the root of its unconvincing theoretical status, as there is no explanation for the existence of such constant for the entire cosmic history. Herein we explore general models of the vacuum energy density slowly evolving with the Hubble function $H$ and/or its time derivative, $\rho_{\Lambda}(H,\dot{H})$. Some of these models are actually well-motivated from the theoretical point of view and may provide a rich phenomenology that could be explored in future observations, whereas some others have more limitations. In this work, we put them to the test and elucidate which ones are still compatible with the present observations and which ones are already ruled out. We consider their implications on structure formation, in combination with data on type Ia supernovae, the Cosmic Microwave Background, the Baryonic Acoustic Oscillations, and the predicted redshift distribution of cluster-size collapsed structures. The relation of these vacuum models on possible evidence of dynamical dark energy recently pointed out in the literature is also briefly addressed. \\ ( http://arxiv.org/abs/1409.7048 , 457kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7073 (*cross-listing*) Date: Wed, 24 Sep 2014 20:01:05 GMT (11kb) Title: 'The End' Authors: Nemanja Kaloper, Antonio Padilla Categories: hep-th astro-ph.CO gr-qc hep-ph Comments: LaTeX, 8 pages \\ Recently we proposed a mechanism for sequestering the Standard Model vacuum energy that predicts that the universe will collapse. Here we present a simple mechanism for bringing about this collapse, employing a scalar field whose potential is linear and becomes negative, providing the negative energy density required to end the expansion. The slope of the potential is chosen to allow for the expansion to last until the current Hubble time, about $10^{10}$ years, to accommodate our universe. Crucially, this choice is technically natural due to a shift symmetry. Moreover, vacuum energy sequestering selects {\it radiatively stable} initial conditions for the collapse, which guarantee that immediately before the turnaround the universe is dominated by the linear potential which drives an epoch of accelerated expansion for at least an efold. Thus a single, technically natural choice for the slope ensures that the collapse is imminent and is preceded by the current stage of cosmic acceleration, giving a new answer to the 'Why Now?' problem. \\ ( http://arxiv.org/abs/1409.7073 , 11kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7502 (*cross-listing*) Date: Fri, 26 Sep 2014 09:00:46 GMT (86kb) Title: Black holes as particle accelerators: a brief review Authors: Tomohiro Harada and Masashi Kimura Categories: gr-qc astro-ph.HE hep-ph hep-th Comments: 25 pages, 5 figures, accepted for publication in Classical and Quantum Gravity as a Topical Review Report-no: RUP-14-11 \\ Rapidly rotating Kerr black holes can accelerate particles to arbitrarily high energy if the angular momentum of the particle is fine-tuned to some critical value. This phenomenon is robust as it is founded on the basic properties of geodesic orbits around a near-extremal Kerr black hole. On the other hand, the maximum energy of the acceleration is subjected to several physical effects. There is convincing evidence that the particle acceleration to arbitrarily high energy is one of the universal properties of general near-extremal black holes. We also discuss gravitational particle acceleration in more general context. This article is intended to provide a pedagogical introduction to and a brief overview of this topic for non-specialists. \\ ( http://arxiv.org/abs/1409.7502 , 86kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7545 (*cross-listing*) Date: Fri, 26 Sep 2014 11:50:03 GMT (803kb,D) Title: Strong-coupling Jet Energy Loss from AdS/CFT Authors: R. Morad and W. A. Horowitz Categories: hep-th hep-ph Comments: 28 pages, 9 figures \\ We propose a novel definition of a holographic light hadron jet and consider the phenomenological consequences, including the very first fully self-consistent, completely strong-coupling calculation of the jet nuclear modification factor $R_{AA}$, which we find compares surprisingly well with recent preliminary data from LHC. We show that the thermalization distance for light parton jets is an extremely sensitive function of the \emph{a priori} unspecified string initial conditions and that worldsheets corresponding to non-asymptotic energy jets are not well approximated by a collection of null geodesics. Our new string jet prescription, which is defined by a separation of scales from plasma to jet, leads to the re-emergence of the late-time Bragg peak in the instantaneous jet energy loss rate; unlike heavy quarks, the energy loss rate is unusually sensitive to the very definition of the string theory object itself. A straightforward application of the new jet definition leads to significant jet quenching, even in the absence of plasma. By renormalizing the in-medium suppression by that in the vacuum we find qualitative agreement with preliminary CMS $R_{AA}^{jet}(p_T)$ data in our simple plasma brick model. We close with comments on our results and an outlook on future work. \\ ( http://arxiv.org/abs/1409.7545 , 803kb) ------------------------------------------------------------------------------ \\ arXiv:1409.7644 (*cross-listing*) Date: Fri, 26 Sep 2014 17:43:07 GMT (97kb) Title: Evidence of $\Upsilon(1S) \to J/\psi+\chi_{c1}$ and search for double-charmonium production in $\Upsilon(1S)$ and $\Upsilon(2S)$ decays Authors: Belle Collaboration: S.
