Roberge-Weiss transitions at different center symmetry breaking patterns in a ${\mathbb{Z}}_3$-QCD model

Xiu-Fei Li, Zhao Zhang

We study how the Roberge-Weiss (RW) transition depends on the pattern of center symmetry breaking using a ${\mathbb{Z}}_3$-QCD model. We adopt flavor-dependent quark imaginary chem…
