Quark-gluon thermodynamics with the Bbb Z3 symmetry
Abstract
We propose a simple model with the Bbb Z3 symmetry in order to answer whether the symmetry is a good concept in QCD with light quark mass. The model is constructed by imposing the flavor-dependent twisted boundary condition (TBC) on the three-flavor Polyakov-loop extended Nambu-Jona-Lasinio model. In the model, the Bbb Z3 symmetry is preserved below some temperature Tc, but spontaneously broken above Tc. Dynamics of the simple model is similar to that of the original PNJL model without the TBC, indicating that the Bbb Z3 symmetry is a good concept. We also investigate the interplay between the Bbb Z3 symmetry and the emergence of the quarkyonic phase.
