Searches for new physics at SND@LHC

A bstract SND@LHC is an approved experiment equipped to detect scatterings of neutrinos produced in the far-forward direction at LHC, and aimed measure their properties. In addition, detector has a potential search for new feebly interacting particles (FIPs) that may be proton-proton collisions. this paper, we discuss signatures physics two classes particles: stable FIPs detected via scattering, unstable decay inside detector. We estimate sensitivity probe leptophobic dark matter decays neutrino, scalar, vector portal particles. Finally, also compare qualitatively analyze FASER/FASER ? experiments these searches.
