Masses of positive-parity and negative-parity diquarks are investigated at finite temperature
with a quark chemical potential. We employ the three-flavor Nambu-Jona-Lasinio model, in …

The spectrum of the doubly heavy baryons (DHBs) is estimated with respect to the new
observation from the LHCb collaboration (Aaij et al (LHCb Collaboration) 2017 Phys. Rev …

We study the phase structure of dense hadronic matter including Δ (1232) as well as N (939)
based on the parity partner structure, where the baryons have their chiral partners with a …

We construct nuclear matter based on an extended parity doublet model including four light
nucleons, N (939), N (1440), N (1535), and N (1650). We exclude some values of the chiral …

Masses of the singly heavy baryons (SHBs), composed of a heavy quark and a light diquark,
are studied from the viewpoints of heavy-quark spin symmetry (HQSS) and chiral-symmetry …

In-medium interactions of ω-mesons in infinite nuclear matter and finite nuclei are
investigated in a microscopic approach, focused on the particle-hole excitations of the …

I investigate modifications of mass and decay width of N*(1535) in nuclear matter in a chiral
symmetric way. The nucleon and N*(1535) are introduced by a parity doublet model, and …

Finite-volume effects for the nucleon chiral partners are studied within the framework of the
parity-doublet model. Our model includes the vacuum energy shift for nucleons, which is the …

We investigate the interplay between the (light-light quark) chiral condensate and heavy-
light quark condensate induced by the QCD Kondo effect, which is described by an effective …

We investigate the influence of the Kondo effect, namely, the nonperturbative effect induced
by heavy impurities, on the chiral separation effect (CSE) in quark matter. We employ a …
