High-energy collisions at the Large Hadron Collider (LHC) have traditionally focused on particle production at small pseudorapidities. However, to further utilize the valuable data from particles produced at the ATLAS interaction point along the beamline, the proposed Forward Physics Facility (FPF) aims to study particle production in the far-forward region at the high-luminosity LHC. The FPF will house a suite of experiments with the ability of enhancing hadronic interaction models by measurement of the resulting neutrino fluxes. 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 in the far-forward region from proton-proton collisions at ATLAS, analyzing final state particles propagated to this new facility. Results from this simulation provide theoretical expectations for the neutrino fluxes at the FPF, offering insights to refine hadronic interaction models, including the most recently developed, and better estimate atmospheric neutrino backgrounds in astrophysical neutrino telescopes.
