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…
