The far-forward region of the LHC provides a unique opportunity to search for new particles and to study neutrinos at energies beyond those accessible at conventional accelerator-based neutrino experiments. Located 480 m downstream of the ATLAS interaction point, FASER was designed to exploit this largely unexplored physics potential.

In this seminar, recent results from the FASER experiment using Run 3 proton-proton collision data will be presented. These include searches for new, weakly coupled particles and other unconventional signatures, as well as measurements of neutrino interactions at TeV energies using both the FASERν emulsion detector and FASER’s electronic detector. Together, these results demonstrate the broad physics programme enabled by the intense flux of highly collimated particles produced in the far-forward direction at the LHC.

The prospects for FASER in Run 4 will also be discussed, including planned detector upgrades that will extend its capabilities for both searches for physics beyond the Standard Model and precision studies of high-energy neutrinos.
