Title |
Thermodynamics of the vector meson extended quark-meson model |
|
Abstract |
We investigate the effects of (axial)vector mesons on the chiral phase
transition of the model containing 2+1 constituent quarks and Polyakov-loop
degrees of freedom. A chi^2 minimization procedure is used to parameterize
the model based on tree-level decay widths and vacuum scalar and
pseudoscalar curvature masses which includes the vacuum and thermal
contribution of the constituent quarks. The pressure and the derived
thermodynamical observables determined from it at finite temperature T and
chemical potential µ using a simple approximation for the grand potential
are compared to lattice results. The best parametrization of the model
allows for the existence of the critical end point (CEP) of the µ–T phase
diagram. |
