Large enhancement from freeze out
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
distribution increases with increasing , in agreement with recently
measured SPS pion and spectra.Comment: 8 pages, 1 figure. Accepted for publication in Physics Letters
Freeze-out in hydrodynamical models in relativistic heavy ion collisions
Freeze-out of particles across 3-dimensional space-time hypersurface with
space-like normal is discussed in a simple kinetic model. The final momentum
distribution of emitted particles shows a non-exponential transverse momentum
spectrum, which is in quantitative agreement with recently measured SPS pion
and spectra.Comment: 4 pages, 1 figure. Quark Matter'99 Proceeding
