 TMDs and Monte Carlo Event Generators / Hautmann, F. (Oxford U. ; Antwerp U. ; Basque U., Bilbao ; CERN) We discuss prospects for Monte Carlo event generators incorporating the dynamics of transverse momentum dependent (TMD) parton distribution functions. [...] arXiv:1907.03353. - 8 p. Fulltext

 Quantum Fishchain in $AdS_5$ / Gromov, Nikolay (King's Coll. London, Dept. Math ; St. Petersburg, INP) ; Sever, Amit (Tel Aviv U. ; CERN) In our previous paper we derived the holographic dual of the planar fishnet CFT in four dimensions. [...] arXiv:1907.01001. - 39 p. Fulltext

 Measurements of triple-differential cross sections for inclusive isolated-photon+jet events in pp collisions at $\sqrt{s} =$ 8 TeV Measurements are presented of the triple-differential cross section for inclusive isolated-photon+jet events in pp collisions at $\sqrt{s} =$ 8 TeV as a function of photon transverse momentum (${p_{\mathrm{T}}^{\gamma}}$), photon pseudorapidity (${\eta^{\gamma}}$), and jet pseudorapidity (${\eta^{\text{jet}}}$).

 Precision measurement of the $\Lambda_c^+$, $\Xi_c^0$, and $\Xi_c^+$ baryon lifetimes / LHCb Collaboration We report measurements of the lifetimes of the $\Lambda_c^+$, $\Xi_c^+$ and $\Xi_c^0$ charm baryons using proton-proton collision data at center-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3.0 fb$^{-1}$, collected by the LHCb experiment.

 The Upgrade of the CMS Inner Tracker for HL-LHC / Backhaus, Malte (Zurich, ETH) /CMS Collaboration During the Long Shutdown (LS) from 2024 to 2026 the Large Hadron Collider (LHC) will be upgraded in order to provide a ten-fold increase of the data rate to the experiments. This will enhance the sensitivity of the experiments to possible unexplored rare processes and to allow for precision measurements of known processes, in particular of the properties of the Higgs Boson which was discovered in 2012.

 Towards a determination of the low $x$ gluon via exclusive $J/\psi$ production / Flett, Chris A. ; Jones, Stephen P. ; Martin, Alan D. ; Ryskin, Misha G. ; Teubner, Thomas We discuss how the stability of the theoretical prediction for exclusive $J/\psi$ photoproduction has been improved through a systematic taming of the known $\overline{\text{MS}}$ coefficient functions by accounting for a formally power suppressed, but numerically significant, correction encoded within a $Q_0$ cut.

 Axion-electron decoupling in nucleophobic axion models / Björkeroth, Fredrik ; Di Luzio, Luca ; Mescia, Federico ; Nardi, Enrico ; Panci, Paolo ; Ziegler, Robert The strongest upper bounds on the axion mass come from astrophysical observations like the neutrino burst duration of SN1987A, which depends on the axion couplings to nucleons, or the white-dwarf cooling rates and red-giant evolution, which involve the axion-electron coupling.
