Strange fireball as an explanation of the muon excess in Auger data

We argue that ultrahigh-energy cosmic-ray collisions in Earth’s atmosphere can probe the strange quark density of the nucleon. These collisions have center-of-mass energies ≳104.6A GeV, where A≥14 is the nuclear baryon number. We hypothesize the formation of a deconfined thermal fireball which under...
