Violations of parity and charge conjugation in the theta vacuum with imaginary chemical potential
Hiroaki Kouno, Yuji Sakai, Takahiro Sasaki +2
Charge conjugation (C) and Parity (P) are exact symmetries at theta =pi and Theta = mu/(iT)=pi, where theta is the parameter of the so-called theta-vacuum, mu is the imaginary quar…

Comparison between LQCD and PNJL model at finite chemical potentials
Yuji Sakai, Takahiro Sasaki, Hiroaki Kouno +1
Lattice QCD has the sign problem at real quark chemical potential. There are some regions with no sign problem; one is the imaginary quark chemical potential region and the others…

C and P violations in the PNJL model
Hiroaki Kouno, Yuji Sakai, Takahiro Sasaki +2
Using the PNJL model, we investigate C and P violations when theta =pi and Theta =mu/(iT)=π/3, where T, theta and mu are the temperature, the parameter of theta-vacuum and the quar…
