Description
FASER is a compact, purpose-built experiment at the LHC, investigating long-lived BSM particles and collider neutrinos, located approximately 480m from the ATLAS interaction point. As the first experiment to directly measure collider neutrinos, it continues to probe the previously unexplored energy gap between neutrinos from man-made sources and astrophysical processes. Its latest results use only the electronic components of the detector and a dataset of 177fb-1 collected during the first 3 years of LHC Run 3, to further understand the behaviour of neutrinos at TeV energies. This talk will present the latest studies from FASER on measurements of high-energy neutrino cross sections, focusing on the electron neutrinos, and further interpretation of the results in the beyond SM frameworks.
