Rev. Lett. All figures and tables can be found at http://cms-results.web.cern.ch/cms-results/public-results/publications/HIN-17-003 (CMS Public Pages) Report-no: CMS-HIN-17-003, CERN-EP-2018-076 \\ The elliptic azimuthal anisotropy coefficient ($v_2$) is measured for charm (D$^0$) and strange (K$_\mathrm{S}^0$, $\Lambda$, $\Xi^-$, and $\Omega^-$) hadrons, using a data sample of pPb collisions collected by the CMS experiment, at a nucleon-nucleon center-of-mass energy $\sqrt{s_{_\mathrm{NN}}} =$ 8.16 TeV. A significant positive $v_2$ signal from long-range azimuthal correlations is observed for all particle species in high-multiplicity pPb collisions. The measurement represents the first observation of possible long-range collectivity for open heavy flavor hadrons in small systems. The results suggest that charm quarks have a smaller $v_2$ than the lighter quarks, probably reflecting a weaker collective behavior. This effect is not seen in the larger PbPb collision system at $\sqrt{s_{_\mathrm{NN}}} =$ 5.02 TeV, also presented. \\ ( https://arxiv.org/abs/1804.09767 , 279kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1804.07407 (*cross-listing*) Date: Thu, 19 Apr 2018 23:44:58 GMT (465kb,D) Title: NLO QCD corrections to SM-EFT dilepton and electroweak Higgs boson production, matched to parton shower in POWHEG Authors: Simone Alioli, Wouter Dekens, Michael Girard, Emanuele Mereghetti Categories: hep-ph hep-ex Comments: 37 pages, 8 Figures Report-no: LA-UR-18-23399 \\ We discuss the Standard Model Effective Field Theory (SM-EFT) contributions to neutral- and charge-current Drell-Yan production, associated production of the Higgs and a vector boson, and Higgs boson production via vector boson fusion. We consider all the dimension-six SM-EFT operators that contribute to these processes at leading order, include next-to-leading order QCD corrections, and interface them with parton showering and hadronization in Pythia8 according to the POWHEG method. We discuss existing constraints on the coefficients of dimension-six operators and identify differential and angular distributions that can differentiate between different effective operators, pointing to specific features of Beyond-the-Standard-Model physics. \\ ( https://arxiv.org/abs/1804.07407 , 465kb) ------------------------------------------------------------------------------ \\ arXiv:1804.09766 (*cross-listing*) Date: Wed, 25 Apr 2018 19:32:12 GMT (591kb,D) Title: Dimension-six electroweak top-loop effects in Higgs production and decay Authors: Eleni Vryonidou, Cen Zhang Categories: hep-ph hep-ex Comments: 39 pages, 9 figures \\ We study the next-to-leading order electroweak corrections to Higgs processes from dimension-six top-quark operators in the Standard Model Effective Field Theory approach. We consider the major production channels, including $WH$, $ZH$, and VBF production at the LHC, and $ZH$, VBF production at future lepton colliders, as well as the major decay channels including $H\to \gamma\gamma, \gamma Z, Wl\nu,Zll,b\bar b,\mu\mu,\tau\tau$. The results show that within the current constraints, top-quark operators can shift the signal strength of the loop-induced processes, i.e. $H\to \gamma\gamma,\gamma Z$, by factors of $\sim\mathcal{O}(1)-\mathcal{O}(10)$, and that of the tree-level processes, i.e. all remaining production and decay channels, by $\sim5-10\%$ at the LHC, and up to $\sim15\%$ at future lepton colliders. This implies that essentially all Higgs channels have started to become sensitive to top-quark couplings, and in particular, Higgs observables at high luminosity LHC as well as future lepton colliders, even below the $t\bar t$ threshold, will improve our knowledge of top-quark couplings. We derive the sensitivities of Higgs measurements to top-quark operators at the high luminosity LHC, using projections for both inclusive and differential measurements. We conclude that treating the dimension-six top-quark sector and the Higgs/electroweak sector separately may not continue to be a good strategy. A global analysis combining Higgs and top-quark measurements is desirable, and our calculation and implementation provide an automatic and realistic simulation tool for this purpose. \\ ( https://arxiv.org/abs/1804.09766 , 591kb) ------------------------------------------------------------------------------ \\ arXiv:1804.09837 (*cross-listing*) Date: Thu, 26 Apr 2018 00:16:25 GMT (124kb) Title: $n$-$\bar n$ oscillations and the neutron lifetime Authors: George K. Leontaris, John D. Vergados Categories: hep-ph hep-ex hep-th Comments: 17 pages \\ Neutron-antineutron oscillations are considered in the light of recently proposed particle models, which claim to resolve theneutron lifetime anomaly, indicating the existence of baryon violating $\Delta B=1$ interactions. Possible constraints are derived coming from the non-observation of neutron-antineutron oscillations, which can take place if the dark matter particle produced in neutron decay happens to be a Majorana fermion. It is shown that this can be realised in a simple MSSM extention where only the baryon number violating term $u^cd^cd^c$ is included whilst all other R-parity violating terms are prevented to avoid rapid proton decay. It is demostrated how this scenario can be implemented in a string motivated GUT broken to MSSM by fluxes. \\ ( https://arxiv.org/abs/1804.09837 , 124kb) ------------------------------------------------------------------------------ \\ arXiv:1804.10011 (*cross-listing*) Date: Thu, 26 Apr 2018 12:10:49 GMT (149kb) Title: The Higgs boson $ZZ$ couplings in the Higgs-strahlung at the ILC Authors: Taras V. Zagoskin and Alexander Yu. Korchin Categories: hep-ph hep-ex Comments: 8 pages, 3 figures \\ We derive the fully differential cross section of the Higgs-strahlung process $f \bar{f} \to Z \to Z (\to f_Z \bar{f}_Z) X (\to f_X \bar{f}_X)$, where $f$, $f_Z$, and $f_X$ are arbitrary fermions and $X$ is a spin-zero particle with arbitrary couplings to $Z$ bosons and fermions. This process with $f = e$ and $X = h$ ($h$ denotes the Higgs boson) is planned to be measured at the ILC. Using the derived fully differential cross section, we can obtain an analytical expression for an observable connected with the Higgs-strahlung and convenient to be measured at the ILC. Thus, as soon as this observable is measured, we will be able to put some constraints on the Higgs boson couplings to a pair of $Z$ bosons. \\ ( https://arxiv.org/abs/1804.10011 , 149kb) ------------------------------------------------------------------------------ \\ arXiv:1804.10024 (*cross-listing*) Date: Thu, 26 Apr 2018 12:48:04 GMT (1847kb,D) Title: Multi-particle azimuthal correlations for extracting event-by-event elliptic and triangular flow in Au$+$Au collisions at $\sqrt{s_{_{NN}}}=200$ GeV Authors: A.

Submitted to Physical Review Letters. Plain text data tables for the points plotted in figures for this and previous PHENIX publications are (or will be) publicly available at http://www.phenix.bnl.gov/papers.html \\ We present measurements of elliptic and triangular azimuthal anisotropy of charged particles detected at forward rapidity $1<|\eta|<3$ in Au$+$Au collisions at $\sqrt{s_{_{NN}}}=200$ GeV, as a function of centrality. The multiparticle cumulant technique is used to obtain the elliptic flow coefficients $v_2\{2\}$, $v_2\{4\}$, $v_2\{6\}$, and $v_2\{8\}$, and triangular flow coefficients $v_3\{2\}$ and $v_3\{4\}$. Using the small-variance limit, we estimate the mean and variance of the event-by-event $v_2$ distribution from $v_2\{2\}$ and $v_2\{4\}$. In a complementary analysis, we also use a folding procedure to study the distributions of $v_2$ and $v_3$ directly, extracting both the mean and variance. Implications for initial geometrical fluctuations and their translation into the final state momentum distributions are discussed. \\ ( https://arxiv.org/abs/1804.10024 , 1847kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1708.01798 (*cross-listing*) replaced with revised version Wed, 25 Apr 2018 22:34:35 GMT (2944kb,D) Title: Picosecond timing of Microwave Cherenkov Impulses from High-Energy Particle Showers Using Dielectric-loaded Waveguides Authors: P.
