摘要：

We consider the hydrodynamic evolution of a hot droplet of quark-gluon plasma, taking the emission of hadrons from the surface of the droplet into account. The emission rates are estimated using detailed balance arguments for an evaporation process. We find that for droplets of low temperature the emission rate of baryons may well compete with that of pions. An important characteristic of the emission processes is that for reasonable values of the vacuum energy, the emission of a baryon leads to a heating rather than a cooling of the plasma. Thus the formation of long-lived cold plasma droplets is, even for non-zero net strangeness, very unlikely. © 1990.
