Large $p_t$ enhancement from freeze out

Nuclear Theory 2009-10-31 v1

Abstract

Freeze out of particles across three dimensional space-time hypersurface is discussed in a simple kinetic model. The final momentum distribution of emitted particles, for freeze out surfaces with space-like normal, shows a non-exponential transverse momentum spectrum. The slope parameter of the ptp_t distribution increases with increasing ptp_t, in agreement with recently measured SPS pion and hh^- spectra.
