Abstract:
The question of survivability of quark nuggets against the process of baryon evaporation from their surfaces is discussed within the context of a dynamical model, namely, the chromoelectric flux-tube fission model of baryan formation and evaporation. Depending on the temperature at which nuggets are formed in the early universe and the value of the bag constant B, our conservative estimates (we overestimate the baryan evaporation rate) show that quark nuggets with initial baryan number~ 10/sup 44 or more can survive the evaporation process and be present in the universe today.
