Abstract:
The question of the survivability of quark nuggets against the process of baryon evaporation from their surfaces is studied within the context of a dynamical model, namely, the chromoelectric flux-tube fission model of baryon formation and evaporation. Depending on the temperature at which nuggests are formed in the early Universe and the value of the bag constant B, our conservative estimates (we overestimate the baryon evaporation rate) show that quark nuggets with an initial baryon number ~1044 or more can survive the evaporation process and be present in the Universe today.
