Muon flux measurements at SND@LHC for the LHC p+O run — •Jannis Thienel, Heiko Lacker, and Eduard Ursov — Humboldt-Universität zu Berlin

The Scattering and Neutrino Detector at LHC (SND@LHC) has collected data from various runs of proton-proton (pp) collisions at the ATLAS interaction point (IP1) of the LHC in a previously unexplored pseudo-rapidity range of 7.2 < η < 8.4. The analyses of these runs have successfully demonstrated the detection of (high-energy) neutrinos, including the first detection of muon-neutrino charged-current interactions. Muon flux measurements are essential to quantify one of the backgrounds to neutrino measurements and to verify Monte Carlo simulations. A dedicated investigation of the muon flux in the very forward direction from the p+O collisions at SND@LHC might be of interest for testing hadronic interaction models relevant for cosmic airshower physics. First preliminary results of these muon flux measurements will be presented.
