Higher-Fock States and the Covariance of the Light-Front Quark Model
Ho-Meoyng Choi, Chueng-Ryong Ji
The light-front quark model has been successful in describing various meson properties. We apply the model to the meson weak decays and discuss the covariance of the model. We find…
New effective treatment of the light-front nonvalence contribution in timelike exclusive processes
Chueng-Ryong Ji, Ho-Meoyng Choi
We discuss a necessary nonvalence contribution in timelike exclusive processes. Following a Schwinger-Dyson type of approach, we relate the nonvalence contribution to an ordinary l…
Flow equations for quark-gluon interactions in light-front QCD
Elena Gubankova, Chueng-Ryong Ji, Stephen R. Cotanch
The flow-equation method of continuous unitary transformations is used to eliminate the minimal quark-gluon interaction in the light-front quantized QCD Hamiltonian. The coupled di…
B-Physics Phenomenology with Emphasis on the Light-Cone
Chueng-Ryong Ji, Ho-Meoyng Choi
Theoretical overviews on the B-physics are presented with an emphasis on the light-cone degrees of freedom. Our new treatment of the embedded states seems to give an encouraging re…
Regularizing the Divergent Structure of the Light-Front Currents
Bernard L. G. Bakker, Ho-Meoyng Choi, Chueng-Ryong Ji
The divergences appearing in the 3+1 dimensional fermion-loop calculations are often regulated by smearing the vertices in a covariant manner. Performing a parallel light-front cal…
Flow Equations for Gluodynamics in the Coulomb Gauge
Elena Gubankova, Chueng-Ryong Ji, Stephen R. Cotanch
A systematic procedure to consistently formulate a field theoretical, QCD bound state problem with a fixed number of constituents is outlined. The approach entails applying the Ham…
