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…
