Description
The muon excess in cosmic ray data can be traced back to uncertainties on the hadronic energy fraction after forward interactions. These uncertainties could be addressed by the Forward Physics Facility (FPF) if neutrino measurements will be able to constrain the charged pion to kaon ratio and the charm production in very forward interactions.
I will discuss a "fireball" model which increases the effective hadronic energy fraction in an attempt to resolve the muon excess, and how its physical nature could be probed by measurements at the FPF.
