Description
Measurements of neutrino fluxes at the Forward Physics Facility can be used to study predictions of hadronic interaction models. These advancements are critical for astroparticle physics, linking forward scattering processes to extensive air showers and improving our understanding of cosmic-ray interactions. This work investigates simulated neutrino fluxes at the FPF, focusing in particular on the ratio of electron neutrino to muon neutrino fluxes. Due to their distinct origin and energy spectra, these fluxes may be differentiated, providing an indirect method for determining the ratio of charged kaons to pions. We present simulation studies of the theoretical expectations of the neutrino fluxes at FASER𝝂2 and FLArE. These results will offer insights to refine hadronic interaction models, including the most recently developed, and better estimate atmospheric neutrino backgrounds in astrophysical neutrino telescopes.
