Precision measurement of the $\Lambda_c^+$, $\Xi_c^0$, and $\Xi_c^+$ baryon lifetimes
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. [...]

Double Higgs boson production at NLO: combining the exact numerical result and high-energy expansion / Davies, Joshua ; Heinrich, Gudrun ; Jones, Stephen P. ; Kerner, Matthias ; Mishima, Go ; Steinhauser, Matthias ; Wellmann, David
We consider the next-to-leading order QCD corrections to Higgs boson pair production, using our recent calculation of the form factors in the high-energy limit. [...]

Primordial black hole (PBH) dark matter (DM) non-linear small-scale structure formation begins before the epoch of recombination due to large Poisson density fluctuations. [...]

Measurement of the jet mass in high transverse momentum $Z(\rightarrow b\overline{b})\gamma$ production at $\sqrt{s}= 13$ TeV using the ATLAS detector / ATLAS Collaboration
The integrated fiducial cross-section and unfolded differential jet mass spectrum of high transverse momentum $Z\rightarrow b\overline{b}$ decays are measured in $Z\gamma$ events in proton-proton collisions at $\sqrt{s} = 13$ TeV. [...]

Highly occupied gauge theories in 2+1 dimensions: self-similar attractor / Boguslavski, K. ; Kurkela, A. ; Lappi, T. ; Peuron, J.
Motivated by the boost-invariant Glasma state in the initial stages in heavy-ion collisions, we perform classical-statistical simulations of SU(2) gauge theory in 2+1 dimensional space-time both with and without a scalar field in the adjoint representation. [...]
