Search for anomalous triple gauge couplings in WW and WZ production in lepton + jet events in proton-proton collisions at $\sqrt{s} = $ 13 TeV
A search is presented for three additional operators that would lead to anomalous WW$ \gamma $ or WWZ couplings with respect to those in the standard model. [...]

Measurement of differential cross sections and charge ratios for $t$-channel single top quark production in proton-proton collisions at $\sqrt{s}=$ 13 TeV
A measurement is presented of differential cross sections for $t$-channel single top quark and antiquark production in proton-proton collisions at a centre-of-mass energy of 13 TeV by the CMS experiment at the LHC. [...]

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. [...]
