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…
