Surface Tension at Finite Tempearture in the MIT Bag Model

Abstract

At $ T = 0 $ the surface tension $ σ^{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 differ from hadron to hadron. We also find that the dynamics of the Quark-Gluon Plasma is such that the creation of hybrids $(s\bar{s}g)$ with massive quarks will predominate over the creation of $ (s\bar{s}) $ mesons.
