A model consistent with LQCD data on -meson screening mass
Masahiro Ishii, Akihisa Miyahara, Hiroaki Kouno +1
Recently, state-of-art LQCD calculations were done for -meson and -meson screening mass, and . We consider the two-flavor system, and…
A hadron-quark hybrid model reliable for the EoS in MeV
Akihisa Miyahara, Masahiro Ishii, Hiroaki Kouno +1
We present a simple version of hadron-quark hybrid (HQH) model in the -- plain, where is temperature and is the baryon-number chemical potential. The model is c…
Extrapolation for meson screening masses from imaginary to real chemical potential
Masahiro Ishii, Akihisa Miyahara, Hiroaki Kouno +1
We first extend our formulation for the calculation of - and -meson screening masses to the case of finite chemical potential . We then consider the imaginary- approach…
Crossover-model approach to QCD phase diagram, equation of state and susceptibilities in the 2+1 and 2+1+1 flavor systems
Akihisa Miyahara, Masahiro Ishii, Hiroaki Kouno +1
We construct a simple model for describing the hadron-quark crossover transition by using lattice QCD (LQCD) data in the 2+1 flavor system, and draw the phase diagram in the 2+1 an…
Model prediction for temperature dependence of meson pole masses from lattice QCD results on meson screening masses
Masahiro Ishii, Hiroaki Kouno, Masanobu Yahiro
We propose a practical effective model by introducing temperature () dependence to the coupling strengths of four-quark and six-quark Kobayashi-Maskawa-'t Hooft interactions in…
Temperature dependence of meson screening masses; a comparison of effective model with lattice QCD
Masahiro Ishii, Takahiro Sasaki, Kouji Kashiwa +2
Temperature dependence of pion and sigma-meson screening masses is evaluated by the Polyakov-loop extended Nambu--Jona-Lasinio model with the entanglement vertex (EPNJL model). We…
Determination of restoration from pion and -meson screening masses: Toward the chiral regime
Masahiro Ishii, Koji Yonemura, Junichi Takahashi +2
We incorporate the effective restoration of symmetry in the 2+1 flavor entanglement Polyakov-loop extended Nambu--Jona-Lasinio (EPNJL) model by introducing a tempera…
Determination of the strength of the vector-type four-quark interaction in the entanglement Polyakov-extended Nambu-Jona-Lasino model
Junpei Sugano, Junichi Takahashi, Masahiro Ishii +2
We determine the strength of the vector-type four-quark interaction in the entanglement Polyakov-extended Nambu-Jona-Lasinio (EPNJL) model from the results of recent la…
Effective model approach to meson screening masses at finite temperature
Masahiro Ishii, Takahiro Sasaki, Kouji Kashiwa +2
Temperature dependence of pion and sigma-meson screening masses is evaluated by the Polyakov-loop extended Nambu--Jona-Lasinio (PNJL) model with the entanglement vertex. We propose…
