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…
Entanglement between deconfinement transition and chiral symmetry restoration
Yuji Sakai, Takahiro Sasaki, Hiroaki Kouno +1
We extend the Polyakov-loop extended Nambu-Jona-Lasinio (PNJL) model by introducing an effective four-quark vertex depending on Polyakov loop. The effective vertex generates entang…
Average phase factor in the PNJL model
Yuji Sakai, Takahiro Sasaki, Hiroaki Kouno +1
The average phase factor of the QCD determinant is evaluated at finite quark chemical potential (μ_q) with the two-flavor version of the Polyakov-loop extended Nambu-Jona-Lasinio (…
QCD phase diagram at finite baryon and isospin chemical potentials
Takahiro Sasaki, Yuji Sakai, Hiroaki Kouno +1
The phase structure of two-flavor QCD is explored for thermal systems with finite baryon- and isospin-chemical potentials, mu_B and mu_{iso}, by using the Polyakov-loop extended Na…
Investigation of meson masses for real and imaginary chemical potential
Takeshi Matsumoto, Kouji Kashiwa, Hiroaki Kouno +2
We investigate chemical-potential () and temperature () dependence of scalar and pseudo-scalar meson masses for both real and imaginary , using the Polyakov-loop extended…
