Origin of nucleon mass in the light of PSR J0614-3329 with quark-hadron crossover
Bikai Gao, Yuk-Kei Kong, Yong-Liang Ma
The recent NICER observation of PSR J0614-3329, revealing the smallest reliably measured neutron star radius of km at mass $M = 1.44^{+0.06}_{-0.07} M_\…

Implication of neutron star observations to the origin of nucleon mass
Bikai Gao, Xiang Liu, Masayasu Harada +1
We investigate the implications of neutron star observations for understanding the origin of nucleon mass using a framework that combines three complementary approaches: the equati…

Exploring the first-order phase transition in neutron stars using the parity doublet model and NJL-type quark model
Bikai Gao, Wen-Li Yuan, Masayasu Harada +1
We investigate the possibility and impacts of a first-order phase transition from hadronic matter to quark matter in neutron stars (NSs) using two specific models: the parity doubl…
