Flavor decomposition of the gravitational form factors and mechanical structure of the proton
Hyun-Chul Kim, June-Young Kim, Ho-Yeon Won
We review in the present talk a series of recent works on the flavor decomposition of the gravitational form factors of the proton and its mechanical properties within the framewor…
Multipole structure of the Transition Generalized Parton Distributions
June-Young Kim, Hyun-Chul Kim
We establish the multipole structure of the transition at the level of the generalized parton distributions (GPDs). We decompose the four transition GPDs into one monopol…
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…
Properties of neutron stars and strangeness-mixed stars from a pion mean-field approach
Nam-Yong Ghim, Hyun-Chul Kim, Ulugbek Yakhshiev +1
We investigate the properties of the static neutron stars and strangeness-mixed stars, based on the equations of state derived from a pion mean-field approach. Using the empirical…
Spin-orbit correlations in the nucleon in the large- limit
June-Young Kim, Ho-Yeon Won, Hyun-Chul Kim +1
We study the twist-3 spin-orbit correlations of quarks described by the nucleon matrix elements of the parity-odd rank-2 tensor QCD operator (the parity-odd partner of the QCD ener…
