Abstract

A specific value of light front variable ζ_c(p_T,m) of the inclusively produced hadrons in a relativistic nuclear collision is constructed as a polynomial in transverse momentum p_T of the particle within the UrQMD transport model. It is shown that those particles with the absolute value of their light front variable ζ greater than the corresponding ζ_c(p_T,m) follow a Fermi-Dirac or Bose-Einstein distribution depending upon the spin of the particle.
