タイトル：Origin of Mass from Neutron Star Observations and Hyperon Onset in Dense Matter

アブストラクト：
We investigate the implications of recent neutron star
observations for the origin of nucleon mass within the SU(2) parity doublet
model framework, which naturally incorporates both chiral variant and
chiral invariant mass components. By exploring different quark-hadron phase
transition scenarios, we constrain the allowed range of the chiral
invariant mass component. We further examine the SU(3) parity doublet
structure and demonstrate how the chiral invariant mass influences the
onset density of hyperons in dense matter. Our results establish a direct
connection between neutron star observables and fundamental questions
regarding the nature of hadron mass generation in QCD.
