J/$\psi$ production as a function of charged-particle multiplicity in pp collisions at $\sqrt{s}$ = 5.02 TeV with ALICE / Khatun, Anisa
The relative J/$\psi$ yields as a function of relative charged-particle multiplicity in pp collisions at $\sqrt{s}$ = 5.02 TeV, measured at forward rapidity, are investigated for the first time. [...]

Primordial black holes as dark matter candidate are severely constrained by the Galactic Center 511 keV gamma-ray line / Laha, Ranjan
We derive the strongest constraint on the fraction of dark matter that can be composed of low mass primordial black holes by using the observation of the Galactic Center 511 keV gamma-ray line. [...]

Searching for muonic forces with the ATLAS detector / Galon, Iftah ; Kajamovitz, Enrique ; Shih, David ; Soreq, Yotam ; Tarem, Shlomit
The LHC copiously produces muons via different processes, and the muon sample will be large at the high-luminosity LHC (HL-LHC). [...]

DsTau: Study of tau neutrino production with 400 GeV protons from the CERN-SPS / DsTau Collaboration
In the DsTau experiment at the CERN SPS, an independent and direct way to measure tau neutrino production following high energy proton interactions was proposed. [...]

Real-time discrimination of photon pairs using machine learning at the LHC / Benson, Sean ; Casais Vidal, Adrián ; Cid Vidal, Xabier ; Puig Navarro, Albert
ALPs and other as-yet unobserved $B$ decays to di-photon final states are a challenge to select in hadron collider environments due to the large backgrounds that come directly from the $pp$ collision. [...]

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