摘要

Recent calculations using a chromoelectric flux tube model have shown that the phase boundary between the quark-gluon plasma and the hadron gas may have a low baryon penetrability. The consequences of this result for the evolution of baryon number density during the QCD phase transition are explored, using a two-zone approximation. Very-high-amplitude baryon number density fluctuations result in a wide variety of cases; in some cases nuclear matter densities are approached, which might lead to the formation of strange matter.
