Octet and decuplet baryon -terms and mass decompositions
P. M. Copeland, Chueng-Ryong Ji, W. Melnitchouk
We present a comprehensive analysis of the SU(3) octet and decuplet baryon masses and -terms using high-precision lattice QCD data and chiral SU(3) effective theory with finite…
Beam Spin Asymmetry in Electroproduction of Pseudoscalar or Scalar Meson Production off the Scalar Target
Chueng-Ryong Ji, Ho-Meoyng Choi, Andrew Lundeen +1
We discuss the electroproduction of pseudoscalar () or scalar () meson production off the scalar target. The most general formulation of the differential cross sect…
Constraints on asymmetry of the proton in chiral effective theory
X. G. Wang, Chueng-Ryong Ji, W. Melnitchouk +3
We compute the asymmetry in the proton in chiral effective theory, using phenomenological constraints based upon existing data. Unlike previous meson cloud model calcula…
Comment on "Taming the pion cloud of the nucleon"
Chueng-Ryong Ji, W. Melnitchouk, A. W. Thomas
In a recent Letter, Alberg and Miller presented a calculation of the pion contributions to the self-energy of the nucleon computed from a pseudoscalar (PS) pion-nucleon interaction…
Light-Front Dynamic Analysis of Bound States in Scalar Field Model
Chueng-Ryong Ji, Yukihisa Tokunaga
The light-front dynamics (LFD) of the scalar field model theory is analyzed to solve the two-body bound-state problem. The light-front two-body bound-state equation is extended to…
Equivalence of pion loops in equal-time and light-front dynamics
Chueng-Ryong Ji, W. Melnitchouk, A. W. Thomas
We demonstrate the equivalence of the light-front and equal-time formulations of pionic corrections to nucleon properties. As a specific example, we consider the self-energy of a n…
