Abstract: The LHC produces an intense beam of highly energetic neutrinos of all three flavors in the forwarddirection, and the Forward Physics Facility (FPF) has been proposed to house a suite of experimentstaking advantage of this opportunity. In this study, we investigate the FPF’s potential to probe theneutrino electromagnetic properties, including neutrino millicharge, magnetic moment, and chargeradius. We find that, due to the large flux of tau neutrinos at the LHC, the FPF detectors willbe able to provide the strongest laboratory-based sensitivity to the tau neutrino magnetic momentand millicharge by searching for excess in low recoil energy electron scattering events. We alsofind that, by precisely measuring the rate of neutral current deep inelastic scattering events, theFPF detectors have the potential to obtain the strongest experimental bounds on the neutrinocharge radius for the electron neutrino, and one of the leading bounds for the muon neutrino flavor.The same signature could also be used to measure the weak mixing angle, and we estimate thatsin2θW could be measured to about 3% precision at a scale Q ∼ 10 GeV, shedding new light on thelong-standing NuTeV anomaly
