HOT NUCLEAR-MATTER IN THE QUARK MESON COUPLING MODEL

We study here hot nuclear matter in the quark meson coupling model whi ch incorporates explicitly quark degrees of freedom, with quarks coupl ed to scalar and vector mesons. The equation of state of nuclear matte r including the composite nature of the nucleons is calculated at fini te temperatures. The calculations are done taking into account the med ium-dependent bag constant. Nucleon properties at finite temperatures as calculated here are found to be appreciably different from the valu e at T = 0.
