• Title: Extended Fourier Transformation - A New Perspective Connecting Real Space and Fock Space

Abstract:

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.
