Parity doublet model for baryon octets: diquark classifications and mass hierarchy based on the quark-line diagram
Takuya Minamikawa, Bikai Gao, Toru kojo +1
We construct invariant parity doublet models within the linear realization of the chiral symmetry. Describing baryons as the supe…
Neutron star matter based on a parity doublet model including the meson
Yuk Kei Kong, Takuya Minamikawa, Masayasu Harada
We study the effect of the isovector-scalar meson (980) on the properties of nuclear matter and the neutron star (NS) matter by constructing a parity doublet model with includ…
Chiral restoration of nucleons in neutron star matter: studies based on a parity doublet model
Takuya Minamikawa, Bikai Gao, Toru kojo +1
We review the chiral variant and invariant components of nucleon masses and its consequence on the chiral restoration in extreme conditions, neutron star matter in particular. We c…
Impacts of anomaly on nuclear and neutron star equation of state based on a parity doublet model
Bikai Gao, Takuya Minamikawa, Toru Kojo +1
We examine the role of the anomaly in a parity doublet model of nucleons which include the chiral variant and invariant masses. Our model expresses the anomaly by…
Chiral condensates for neutron stars in hadron-quark crossover; from a parity doublet nucleon model to an NJL quark model
Takuya Minamikawa, Toru Kojo, Masayasu Harada
In this contribution, we summarize our recent studies on the chiral invariant mass and the chiral condensates in neutron star matter. We construct a unified equations of state assu…
Chiral condensates for neutron stars in hadron-quark crossover: from a parity doublet nucleon model to an NJL quark model
Takuya Minamikawa, Toru Kojo, Masayasu Harada
We study the chiral condensates in neutron star matter from nuclear to quark matter domain. We describe nuclear matter with a parity doublet model (PDM), quark matter with the Namb…
Quark-hadron crossover equations of state for neutron stars: constraining the chiral invariant mass in a parity doublet model
Takuya Minamikawa, Toru Kojo, Masayasu Harada
We construct an equation of state (EOS) for neutron stars by interpolating hadronic EOS at low density and quark EOS at high density. A hadronic model based on the parity doublet s…
