Probing soft signals of gravitational-wave memory with space-based interferometers

Yan Cao, Yong-Liang Ma, Yong Tang

Gravitational-wave displacement memory is a remarkable and ubiquitous phenomenon predicted by general relativity, which has not yet been detected. Unlike the oscillatory components…

Origin of hadron mass from gravitational D-form factor and neutron star measurements

Mamiya Kawaguchi, Masayasu Harada, Yong-Liang Ma

Clarifying the origin of hadron mass is one of the fundamental problems in particle physics, relevant from hadronic scales to astrophysical observations. At low energies, this issu…

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…
