Meta-stable States in Quark-Gluon Plasma

We study the meta-stable states in high temperature phase of QCD characterised by nonzero expectation values for the imaginary part of the Polyakov loop. We consider $N_f= 2, 3$ dynamical staggered quarks, and carry out simulations at various values of the coupling $β$ to observe these states. In particular, we find the value of the coupling ($β_m$) above which the meta-stable states appear. The resulting value of $β_m$ corresponds to temperature $T_m \gtrsim 750$MeV for $N_f=2$.
