GLUON CONDENSATES, QUARK MATTER EQUATION OF STATE AND QUARK STARS

We consider here quark matter equation of state including strange quar ks and taking into account a nontrivial vacuum structure for QCD with gluon condensates. The parameters of condendsate function are determin ed from minimisation of the thermodynamic potential. The scale paramet er of the gluon condensates is fixed from the SVZ parameter in the con text of QCD sum rules at zero temperature and zero baryon density. The equation of state for strange matter at zero temperature as derived i s used to study quark star structure using Tolman Oppenheimer Volkoff equations. Stable solutions for quark stars are obtained with a large Chandrasekhar limit as 3.2 M. and radii around 17 kms.
