Rev. D Report-no: BABAR-PUB-18/005, SLAC-PUB-17286 \\ The decay $\tau^{-}\to K^{-}K_S\nu_{\tau}$ has been studied using $430\times10^6$ $e^+e^-\to \tau^+\tau^-$ events produced at a center-of-mass energy around 10.6 GeV at the PEP-II collider and studied with the BABAR detector. The mass spectrum of the $K^{-}K_S$ system has been measured and the spectral function has been obtained. The measured branching fraction ${\cal B}(\tau^{-}\to K^{-}K_S\nu_{\tau}) = (0.739\pm 0.011(\rm stat.)\pm 0.020(\rm syst.))\times 10^{-3}$ is found to be in agreement with earlier measurements. \\ ( https://arxiv.org/abs/1806.10280 , 86kb) ------------------------------------------------------------------------------ \\ arXiv:1806.10341 Date: Wed, 27 Jun 2018 08:39:47 GMT (5464kb,D) Title: Recent results on charmonium-like (exotic) XYZ states at the BESIII/BEPCII experiment in Beijing/China Authors: Frank Nerling (BESIII Collaboration) Categories: hep-ex Comments: 7 pages, 12 figures, Excited QCD 2018 Conference Proceedings, to be published by Acta Physica Polonica B - Proc. Suppl., 10^{th} Workshop on Excited QCD 2018, March 11 - 15, 2018 \\ With about 12 fb$^{-1}$ collected XYZ data sets, BESIII continues the exploration of the exotic charmonium-like states. In this talk, recent results on the measurements of the spin-parity determination of $Z_{\rm c}(3900)$, as well as on line-shapes of $e^+e^- \rightarrow J/\psi\,\pi\pi, h_{\rm c}\pi\pi, \psi(2S)\,\pi^0\pi^0/\pi^+\pi^-$, and $\pi^+ D^0 D^{*-}$ from open charm are discussed. Also, the recent observation of $e^+ e^- \rightarrow \phi \chi_{c1/2}$ at $\sqrt(s)=4.6$ GeV is reported. \\ ( https://arxiv.org/abs/1806.10341 , 5464kb) ------------------------------------------------------------------------------ \\ arXiv:1806.10555 Date: Wed, 27 Jun 2018 16:20:07 GMT (1470kb,D) Title: Search for pair- and single-production of vector-like quarks in final states with at least one $Z$ boson decaying into a pair of electrons or muons in $pp$ collision data collected with the ATLAS detector at $\sqrt{s} = 13$ TeV Authors: ATLAS Collaboration Categories: hep-ex Comments: 74 pages in total, author list starting page 58, 17 figures, 18 tables, submitted to Phys. Rev. D. All figures including auxiliary figures are available at http://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/PAPERS/EXOT-2016-35 Report-no: CERN-EP-2018-145 \\ A search for vector-like quarks is presented, which targets their decay into a $Z$ boson and a third-generation Standard Model quark. In the case of a vector-like quark $T$ ($B$) with charge $+2/3e$ ($-1/3e$), the decay searched for is $T \rightarrow Zt$ ($B \rightarrow Zb$). Data for this analysis were taken during 2015 and 2016 with the ATLAS detector at the Large Hadron Collider and correspond to 36.1 fb$^{-1}$ of $pp$ collisions at $\sqrt{s} = 13$ TeV. The final state used is characterized by the presence of a $Z$ boson with high transverse momentum, which is reconstructed from a pair of opposite-sign same-flavor leptons, as well as $b$-tagged jets. Pair- and single-production of vector-like quarks are both taken into account and are each searched for using optimized dileptonic exclusive and trileptonic inclusive event selections. In these selections, the high scalar sum of jet transverse momenta, the presence of high-transverse-momentum large-radius jets, as well as - in the case of the single-production selections - the presence of forward jets are used. No significant excess over the background-only hypothesis is found and exclusion limits at 95% confidence level allow masses of vector-like quarks of $m_T > 1030$ GeV ($m_T > 1210$ GeV) and $m_B > 1010$ GeV ($m_B > 1140$ GeV) in the singlet (doublet) model. In the case of 100% branching ratio for $T\rightarrow Zt$ ($B\rightarrow Zb$), the limits are $m_T > 1340$ GeV ($m_B > 1220$ GeV). Limits at 95% confidence level are also set on the coupling to Standard Model quarks for given vector-like quark masses. \\ ( https://arxiv.org/abs/1806.10555 , 1470kb) ------------------------------------------------------------------------------ \\ arXiv:1806.10576 Date: Wed, 27 Jun 2018 17:21:39 GMT (205kb,D) Title: Observation of the decay $\overline{B_s^0} \rightarrow \chi_{c2} K^+ K^- $ Authors: LHCb collaboration: R.

The decay mode $\overline{B_s^0} \rightarrow \chi_{c1} K^+ K^- $ allows the $ B_s^0$ mass to be measured as $m(B_s^0) = 5366.83 \pm 0.25 \pm 0.27 \, \textrm{MeV}/c^2,$ where the first uncertainty is statistical and the second systematic. \\ ( https://arxiv.org/abs/1806.10576 , 205kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1806.10157 (*cross-listing*) Date: Tue, 26 Jun 2018 18:11:19 GMT (1980kb,D) Title: Standard Model Fragmentation Functions at Very High Energies Authors: Christian W Bauer, Davide Provasoli and Bryan R. Webber Categories: hep-ph hep-ex Comments: 32 pages, 4 figures Report-no: Cavendish-HEP-18/12 \\ We compute the leading-order evolution of parton fragmentation functions for all the Standard Model fermions and bosons up to energies far above the electroweak scale, where electroweak symmetry is restored. We discuss the difference between double-logarithmic and leading-logarithmic resummation, and show how the latter can be implemented through a scale choice in the SU(2) coupling. We present results for a wide range of partonic center-of-mass energies, including the polarization of fermion and vector boson fragmentation functions induced by electroweak evolution. \\ ( https://arxiv.org/abs/1806.10157 , 1980kb) ------------------------------------------------------------------------------ \\ arXiv:1806.10591 (*cross-listing*) Date: Wed, 27 Jun 2018 17:48:44 GMT (21kb) Title: On operator relations for gravitational form factors of a spin-0 hadron Authors: Kazuhiro Tanaka (Juntendo Univ.) Categories: hep-ph hep-ex nucl-th Comments: 19 pages Report-no: J-PARC-TH-0120 \\ The gravitational form factors for a hadron, the form factors for the hadron matrix element of the QCD energy-momentum tensor, not only describe the coupling of the hadron with a graviton, but also serve as unique quantities for describing the shape inside the hadron reflecting dynamics of quarks and gluons, such as the internal shear forces acting on the quarks/gluons and their pressure distributions. We consider the quark contribution to the gravitational form factors for a (pseudo)scalar hadron, and derive and clarify the relations satisfied by them as direct consequences of the symmetries and the equations of motion in QCD, and connections to the generalized parton distributions. Our results reveal the connections between the gravitational form factors and the higher-twist quark-gluon correlation effects inside the hadrons. \\ ( https://arxiv.org/abs/1806.10591 , 21kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1710.09126 replaced with revised version Wed, 27 Jun 2018 07:20:22 GMT (1026kb,D) Title: Atmospheric neutrino oscillation analysis with external constraints in Super-Kamiokande I-IV Authors: Super-Kamiokande Collaboration: K.
