Light-front zero-mode issue on the vector meson decay constant
Ho-Meoyng Choi, Chueng-Ryong Ji
We discuss the light-front zero-mode issue in the light-front quark model (LFQM) prediction of a vector meson decay constant from the perspective of the vacuum fluctuation consiste…
Light-Front Quantum Chromodynamics: A framework for the analysis of hadron physics
B. L. G. Bakker, A. Bassetto, S. J. Brodsky +17
An outstanding goal of physics is to find solutions that describe hadrons in the theory of strong interactions, Quantum Chromodynamics (QCD). For this goal, the light-front Hamilto…
Self-consistent covariant description of vector meson decay constants and chirality-even quark-antiquark distribution amplitudes up to twist-3 in the light-front quark model
Ho-Meoyng Choi, Chueng-Ryong Ji
Although the meson decay amplitude described by a two-point function may be regarded as one of the simplest possible physical observable, it is interesting that this apparently sim…
Anatomy of relativistic pion loop corrections to the electromagnetic nucleon coupling
Chueng-Ryong Ji, W. Melnitchouk, A. W. Thomas
We present a relativistic formulation of pion loop corrections to the coupling of photons with nucleons on the light-front. Vertex and wave function renormalization constants are c…
Ideas of Four-Fermion Operators in Electromagnetic Form Factor Calculations
Chueng-Ryong Ji, Bernard L. G. Bakker, Ho-Meoyng Choi +1
Four-fermion operators have been utilized in the past to link the quark-exchange processes in the interaction of hadrons with the effective meson-exchange amplitudes. In this paper…
