Kaon condensation in an excluded volume mean field model with meson exchange interactions

We develop an equation of state for a multicomponent hadron gas in the mean field formalism by incorporating excluded volume corrections arising due t o a hard-core repulsion between a pair of baryons and meson exchange correc tion in the kaon sector. We use this formalism to study the kaon-condensati on problem and find that the kaon-condensation phenomenon is model dependen t. It occurs in our description of it hot and dense hadron gas consisting o f baryons with a hard-core radius of baryons r(N) less than or equal to 0.6 fm, [S0556-2813(99)08005-X].
