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…
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…
Phase structure and Hosotani mechanism in QCD-like theory with compact dimensions
Kouji Kashiwa, Hiroaki Kouno, Takahiro Makiyama +3
We investigated the phase diagram of gauge theory in four dimension with one compact dimension by using the perturbative one-loop effective potential. Effects of the adjoin…
Determination of quark-hadron transition from lattice QCD and neutron-star observation
Takahiro Sasaki, Nobutoshi Yasutake, Michio Kohno +2
We determine the quark-hadron transition line in the whole region of temperature (T) and baryon-number chemical potential (μ_B) from lattice QCD results and neutron-star mass measu…
Differences and similarities between fundamental and adjoint matters in SU(N) gauge theories
Hiroaki Kouno, Tatsuhiro Misumi, Kouji Kashiwa +3
We investigate differences and similarities between fundamental fermions and adjoint fermions in SU(N) gauge theories. The gauge theory with fundamental fermions possesses ZN symme…
Practical approach to the sign problem at finite theta-vacuum angle
Takahiro Sasaki, Hiroaki Kouno, Masanobu Yahiro
We investigate a way of circumventing the sign problem in lattice QCD simulations with a theta-vacuum term, using the PNJL model. We consider the reweighting method for the QCD Lag…
