Research Description
Professor Ji developed a relativistic quark model motivated by the quantum chromodynamics (QCD) to describe the hadron structure and spectrum. He Pioneered the idea of connecting the instant form dynamics and the light-front dynamics and contributed to utilizing the light cone in solving relativistic bound state and scattering problems. He has also made chiral effective theory calculations to study the long distance scale QCD phenomenology as well as perturbative QCD computations of the nucleon, meson and deuteron form factors to understand the structures of hadron and a few hadron systems at short distance scale. Other research accomplishments include an application of nuclear and particle physics to astrophysics and cosmology involving neutron star and dark matter.
