A model consistent with LQCD data on $ρ$ -meson screening mass

Masahiro Ishii, Akihisa Miyahara, Hiroaki Kouno +1

Recently, state-of-art LQCD calculations were done for $π$ -meson and $ρ$ -meson screening mass, $M_{π}^{scr} (T)$ and $M_{ρ}^{scr} (T)$ . We consider the two-flavor system, and…

A hadron-quark hybrid model reliable for the EoS in $μ_{B} \leq 400$ MeV

Akihisa Miyahara, Masahiro Ishii, Hiroaki Kouno +1

We present a simple version of hadron-quark hybrid (HQH) model in the $μ_{B}$ -- $T$ plain, where $T$ is temperature and $μ_{B}$ 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 $π$ - and $σ$ -meson screening masses to the case of finite chemical potential $μ$ . We then consider the imaginary- $μ$ 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…

Equation of state and transition temperatures in the quark-hadron hybrid model

Akihisa Miyahara, Yuhei Torigoe, Hiroaki Kouno +1

We analyze the equation of state of 2+1 flavor lattice QCD at zero baryon density by constructing the simple quark-hadron hybrid model that has both quark and hadron components sim…
