Quadrupole forces between quark/gluon subsystems inside higher-spin particles
June-Young Kim, Hyun-Chul Kim
We generalize the mechanical interpretation of the forces between quark and gluon subsystems, previously studied for the nucleon, to arbitrary higher-spin particles. For spin-0 and…
Gravitational form factors of the nucleon and their mechanical structure: Twist-2 case
Hyun-Chul Kim, June-Young Kim, Ho-Yeon Won
We present a series of recent works on the gravitational form factors (GFFs) of the nucleon within a pion mean-field approach, which is also called the chiral quark-soliton model.…
Nucleon tensor form factors at large
Nam-Yong Ghim, Ho-Yeon Won, June-Young Kim +1
We investigate nucleon tensor form factors in the large- limit. In this picture, the nucleon emerges as a state of the valence quarks, which were bound by pion mean fi…
Nucleon and singly heavy baryons from the QCD instanton vacuum
Yongwoo Choi, Hyun-CHul Kim
We construct an effective chiral theory for the nucleon, based on the low-energy effective QCD partition function from the QCD instanton vacuum. We fully consider the momentum-depe…
