(376 additional authors not shown) Categories: hep-ex Comments: 22 page, 6 figures \\ We report results on the studies of the $e^+e^-\to B_s^{(*)}\bar{B}_s^{(*)}$ processes. The results are based on a $121.4$ fb$^{-1}$ data sample collected with the Belle detector at the center-of-mass energy near the $\Upsilon(10860)$ peak and $16.4$ fb$^{-1}$ of data collected at 19 energy points in the range from 10.77 to 11.02 GeV. We observe a clear $e^+e^-\to\Upsilon(10860)\to B_s^{(*)}\bar{B}_s^{(*)}$ signal, with no statistically significant signal of $e^+e^-\to \Upsilon(11020)\to B_s^{(*)}\bar{B}_s^{(*)}$. The relative production ratio of $B_s^*\bar{B}_s^*$, $B_s\bar{B}_s^{*}$, and $B_s\bar{B}_s$ final states at $\sqrt{s}=10.866$ GeV is measured to be $7:$ $0.856\pm0.106(stat.)\pm0.053(syst.):$ $0.645\pm0.094(stat.)^{+0.030}_{-0.033}(syst.)$. An angular analysis of the $B_s^*\bar{B}_s^*$ final state produced at the $\Upsilon(10860)$ peak is also performed. \\ ( https://arxiv.org/abs/1609.08749 , 103kb) ------------------------------------------------------------------------------ \\ arXiv:1609.08987 Date: Wed, 28 Sep 2016 16:17:20 GMT (313kb,D) Title: Measuring the leading hadronic contribution to the muon g-2 via $\mu\,e$ scattering Authors: G. Abbiendi, C. M. Carloni Calame, U. Marconi, C. Matteuzzi, G. Montagna, O. Nicrosini, M. Passera, F. Piccinini, R. Tenchini, L. Trentadue, G. Venanzoni Categories: hep-ex hep-ph Comments: 8 pages, 4 figures \\ We propose a new experiment to measure the running of the fine-structure constant in the space-like region by scattering high-energy muons on atomic electrons of a low-Z target through the process $\mu e \to \mu e$. The differential cross section of this process, measured as a function of the squared momentum transfer $t=q^2<0$, provides direct sensitivity to the leading-order hadronic contribution to the muon anomaly $a^{\rm{HLO}}_{\mu}$. By using a muon beam of 150 GeV, with an average rate of $\sim1.3\times 10^7$ muon/s, currently available at the CERN North Area, a statistical uncertainty of $\sim 0.3\%$ can be achieved on $a^{\rm{HLO}}_{\mu}$ after two years of data taking. This direct measurement of $a^{\rm{HLO}}_{\mu}$ will provide an independent determination, competitive with the time-like dispersive approach, and consolidate the theoretical prediction for the muon $g$-2 in the Standard Model. It will allow therefore a firmer interpretation of the measurements of the future muon $g$-2 experiments at Fermilab and J-PARC. \\ ( https://arxiv.org/abs/1609.08987 , 313kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1609.08781 (*cross-listing*) Date: Wed, 28 Sep 2016 05:47:39 GMT (1242kb,D) Title: Quark-gluon discrimination in the search for gluino pair production at the LHC Authors: Biplob Bhattacherjee, Satyanarayan Mukhopadhyay, Mihoko M. Nojiri, Yasuhito Sakaki and Bryan R. Webber Categories: hep-ph hep-ex Comments: 22 pages, 8 figures, 1 table Report-no: Cavendish-HEP-16/16, KEK-TH-1936, PITT-PACC 1609 \\ We study the impact of including quark- and gluon-initiated jet discrimination in the search for strongly interacting supersymmetric particles at the LHC. Taking the example of gluino pair production, considerable improvement is observed in the LHC search reach on including the jet substructure observables to the standard kinematic variables within a multivariate analysis. In particular, quark and gluon jet separation has higher impact in the region of intermediate mass-gap between the gluino and the lightest neutralino, as the difference between the signal and the standard model background kinematic distributions is reduced in this region. We also compare the predictions from different Monte Carlo event generators to estimate the uncertainty originating from the modelling of the parton shower and hadronization processes. \\ ( https://arxiv.org/abs/1609.08781 , 1242kb) ------------------------------------------------------------------------------ \\ arXiv:1609.08847 (*cross-listing*) Date: Wed, 28 Sep 2016 10:12:28 GMT (101kb) Title: The energy dependence of the diffraction minimum and new LHC data Authors: O.V. Selyugin Categories: hep-ph hep-ex Comments: 10 pages, 4 figures. arXiv admin note: text overlap with arXiv:1207.0600, arXiv:1505.02426 \\ The soft diffraction phenomena in the elastic proton-proton scattering are reviewed from the viewpoint of experiments at the LHC (TOTEM and ATLAS collaboration). In the framework of the High Energy Generalized Structure (HEGS) model the form of the diffraction minimum in the nucleon-nucleon elastic scattering in a wide energy region is analyzed. The numerical predictions at LHC energies are presented. The comparison of the model predictions with the new LHC data at $\sqrt{s}=13$ TeV is made. \\ ( https://arxiv.org/abs/1609.08847 , 101kb) ------------------------------------------------------------------------------ \\ arXiv:1609.08928 (*cross-listing*) Date: Wed, 28 Sep 2016 14:36:10 GMT (2632kb,D) Title: A review of the open charm and open bottom mesons Authors: Hua-Xing Chen, Wei Chen, Xiang Liu, Yan-Rui Liu and Shi-Lin Zhu Categories: hep-ph hep-ex hep-lat nucl-ex nucl-th Comments: 60 pages, 57 figures, 18 tables, comments and suggestions welcome \\ Since the discovery of the first charmed meson in 1976, many open-charm and open-bottom mesons were observed. In 2003 two narrow charm-strange states $D_{s0}^*(2317)$ and $D_{s1}(2460)$ were discovered by the BaBar and CLEO Collaborations, respectively. After that, more excited heavy mesons were reported. In this work, we review the experimental and theoretical progress in this field. \\ ( https://arxiv.org/abs/1609.08928 , 2632kb) ------------------------------------------------------------------------------ \\ arXiv:1609.08984 (*cross-listing*) Date: Wed, 28 Sep 2016 16:07:31 GMT (493kb,D) Title: Dynamics of the ions in Liquid Argon Detectors and electron signal quenching Authors: L.Romero, R.Santorelli and B.Montes Categories: physics.ins-det hep-ex Comments: 23 pages, 8 figures \\ A study of the dynamics of the positive charges in liquid argon has been carried out in the context of the future massive time projection chambers proposed for dark matter and neutrino physics. The ions spend considerably longer times in the active volume with respect to the electrons given their small mobility coefficient in liquid. The space charge can be additionally increased by the injection in the target volume of the ions produced by electron multiplying devices located in a gas phase above the liquid. The impact of the positive current on the uniformity of the field has been evaluated as well as the probability of the charge signal quenching due to the electron-ion recombination along the drift. The results show a potential concern for the operation of massive detectors with drift of many meters when located on surface. \\ ( https://arxiv.org/abs/1609.08984 , 493kb) ------------------------------------------------------------------------------ \\ arXiv:1609.08994 (*cross-listing*) Date: Wed, 28 Sep 2016 16:29:55 GMT (37kb) Title: Exploring the LHC Landscape with Dileptons Authors: Dimitri Bourilkov Categories: hep-ph hep-ex Comments: 21 pages, 1 table, 11 figures, LaTeX \\ The dilepton decay channels provide clean signatures and are an ideal hunting ground for high mass resonant, like Z', or non-resonant, like contact interactions or extra dimensions, searches at the LHC. The production of high invariant mass opposite sign lepton pairs in proton-proton collisions in the Standard Model is dominated by the Drell-Yan process. In addition to this photon or Z exchange mediated mechanism, photons radiated by the incoming protons can collide and produce lepton pairs. In this paper detailed calculations of the Drell-Yan process at next-to-next-to-leading order in QCD and next-to-leading order in the electroweak corrections, augmented with the photon-induced effects, are presented in the typical acceptance of a multi-purpose LHC detector at center of mass energy 13 TeV. Estimates of the expected backgrounds for new physics searches are provided for dilepton invariant masses up to the LHC kinematic limit. \\ ( https://arxiv.org/abs/1609.08994 , 37kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1512.06249 (*cross-listing*) replaced with revised version Wed, 28 Sep 2016 09:06:25 GMT (1997kb,D) Title: Dark Matter searches using gravitational wave bar detectors: quark nuggets and newtorites Authors: M.Bassan, E.Coccia, S.D'Antonio, V.Fafone, G.
