Neutrino Physics and Search for Light Dark Matter with SND@LHC

The SND@LHC detector is supposed to be ready beginning of 2022 and to take data in Run.3 of the Large Hadron Collider (LHC) in the period 2022-2024. The experiment aims to measure interactions of electron-, muon, and tau-neutrinos, which are produced in LHC proton-proton collisions in the interaction point of the ATLAS experiment, in an energy and pseudo-rapidity range yet unexplored (energies: several 100 GeV up to few TeV; pseudo-rapditities: 7.2-8.6). This not only allows for fundamental tests with neutrinos but also for improving our understanding of the production of high-energy neutrinos in astroparticle neutrino experiments. The aim is to develop calibration and reconstruction methods for muons and hadronic jets produced in neutrino deep-inelastic scattering, based on this work, to significantly contribute to the SND@LHC measurements of such neutrino interactions. They will use these reconstruction methods to search also for light dark matter particles potentially produced in the primary LHC proton-proton interactions in a regime that has not been tested so far.
