Surface tension at finite temperature in the MIT bag model

摘要

At T = 0 the surface tension sigma(1/3) in the MIT bag model for a single hadron is known to be negligible as compared to the bag pressure B-1/4. We show that at finite temperature it has a substantial value of 50-70 MeV which also differs from hadron to hadron. We also find that the dynamics of the Quark-Gluon Plasma is such that the creation of hybrids (s (s) over bar g) with massive quarks will predominate over the creation of (s (s) over bar) mesons.
