Abstract

We investigate the scalar meson mass dependence on the chiral phase\ntransition in the framework of an SU(3), (axial)vector meson extended linear\nsigma model with additional constituent quarks and Polyakov loops. We determine\nthe parameters of the Lagrangian at zero temperature in a hybrid approach,\nwhere we treat the mesons at tree-level, while the constituent quarks at 1-loop\nlevel. We assume two nonzero scalar condensates and together with the\nPolyakov-loop variables we determine their temperature dependence according to\nthe 1-loop level field equations.\n
