Theta vacuum and entanglement interaction in the three-flavor Polyakov-loop extended Nambu-Jona-Lasinio model
Takahiro Sasaki, Junichi Takahashi, Yuji Sakai +2
We investigate theta-vacuum effects on the QCD phase diagram for the realistic 2+1 flavor system, using the three-flavor Polyakov-extended Nambu-Jona-Lasinio (PNJL) model and the e…
Spontaneous parity and charge-conjugation violations at real isospin and imaginary baryon chemical potentials
Hiroaki Kouno, Mizuho Kishikawa, Takahiro Sasaki +2
The phase structure of two-flavor QCD is investigated at real isospin and imaginary quark chemical potentials by using the Polyakov-loop extended Nambu--Jona-Lasinio model. In the…
Quark-mass dependence of the three-flavor QCD phase diagram at zero and imaginary chemical potential: Model prediction
Takahiro Sasaki, Yuji Sakai, Hiroaki Kouno +1
We draw the three-flavor phase diagram as a function of light- and strange-quark masses for both zero and imaginary quark-number chemical potential, using the Polyakov-loop extende…
Theta vacuum effects on QCD phase diagram
Yuji Sakai, Hiroaki Kouno, Takahiro Sasaki +1
Theta vacuum effects on the QCD phase structure in the μ-T plane are studied by using the Polyakov-loop extended Nambu-Jona-Lasinio model and its extension, where μis the quark che…
Equation of state in the PNJL model with the entanglement interaction
Yuji Sakai, Takahiro Sasaki, Hiroaki Kouno +1
The equation of state and the phase diagram in two-flavor QCD are investigated by the Polyakov-loop extended Nambu--Jona-Lasinio (PNJL) model with an entanglement vertex between th…
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…
