摘要: The usual particle emission scenario used in hydrodynamics presupposes that particles instantaneously stop interacting (freeze-out) once they reach some three dimensional surface. Another formalism has been developed recently where occurs continuously during the whole expansion of thermalized matter. Here we compare both mechanisms a simplified hydrodynamical framework and show lead to drastically different interpretation data.
