Thermodynamics of a deformed bag and quark-gluon deconfinement phase transition

Technical Report:

Abstract

Constructing a colour singlet partition function for a finite size deformable bag, the thermodynamic properties of quarks (two flavours) and gluons are studied with the chemical potential {mu} {ne} 0 under the constraint that the baryon number, b = 1. The transition temperature, T{sub S} in the large volume limit as well as the critical temperature, T{sub C} > T{sub S}, beyond which hadrons cease to exist, both are found to decrease with the increase of deformation, presently a spheroidal shape being considered. The difference T{sub C} - T{sub S} {approx} 20 MeV, which arises mainly due to the restriction to the colour singlet states, remains more or less deformation independent. Thus, a region of superheated (supercooled) metastable states in the temperature range T{sub S} < T < T{sub C} in the {mu} - T exists even for deformed hadrons with the values of T{sub S} and T{sub C} somewhat reduced.
