Search for the lepton-flavour violating decays $B^+ \to π^+ μ^\pm e^\mp$

LHCb collaboration, R. Aaij, M. Abdelfatah, A. S. W. Abdelmotteleb et autres

The first search for the lepton-flavour violating decays $B^+ \to π^+ μ^{\pm} e^{\mp}$ in proton-proton collisions is presented, using data collected by the LHCb experiment between 2011 and 2018, corresponding to an integrated luminosity of 9 fb$^{-1}$. No significant signal is observed …

Measurement of di-muons from 400 GeV/c protons interacting in a thick molybdenum/tungsten target

A. Aksoy, R. Albanese, K. Albrecht, F. Alessio et autres

Di-muon events emanating from a replica of the SHiP target at the CERN SPS contain a clear signal of $J/ \psi$ production. The production rate is in reasonable agreement with Monte Carlo based on Pythia v8. For the interval in rapidity defined …

Study of the Run-3 muon flux at the SND@LHC experiment

D. Abbaneo, S. Ahmad, R. Albanese, A. Alexandrov et autres

Long-range muons produced in proton–proton collisions at the ATLAS interaction point constitute the primary background for neutrino interaction searches at the SND@LHC experiment. This work presents a comprehensive characterization of the muon flux throughout LHC Run-3, benchmarking Monte Carlo simulations against experimental …
