Probing QCD approach to thermal equilibrium with ultrahigh energy cosmic rays
Original language description
The Pierre Auger Collaboration has reported an excess in the number of muons of a few tens of percent over expectations computed using extrapolation of hadronic interaction models tuned to accommodate LHC data, Very recently, we proposed an explanation for the muon excess assuming the formation of a deconfined quark matter (fireball) state in central collisions of ultrarelativistic cosmic rays with air nuclei. At the first stage of its evolution the fireball contains gluons as well as u and d quarks. The very high baryochemical potential inhibits gluons from fragmenting into uu¯ and dd¯, and so they fragment predominantly into ss¯ pairs.
