A Heavy Glueball with Color-Singletness Restriction at Finite Temperature

Abstract

We show that a heavy glueball (much heavier than that studied by others which is in the range of 1-2 GeV) is generated in a pure gluon plasma when color-singletness condition is imposed on the partition function at finite temperature. This confirms Abbas's recent prediction (hep-ph/9504430) of the existence of a heavy glueball within the framework of the early universe scenario.
