Light-Front QCD Hamiltonian Dynamics and Constituent Quark Picture in Exclusive Processes

Chueng-Ryong Ji, Ho-Meoyng Choi

After reviewing a connection between quantum chromodynamics and contituent quark model pictures in the light-front quantization with some comparison and contrast to the ordinary eq…

Pion Form Factor and Quark Mass Evolution in a Light-Front Quark Model

Ho-Meoyng Choi, L. S. Kisslinger, Chueng-Ryong Ji

We discuss the soft contribution to the elastic pion form factor with the mass evolution from current to constituent quark being taken into account in a light-front quark model(LFQ…

Light-front quark model analysis of rare decays

Ho-Meoyng Choi, Chueng-Ryong Ji, L. S. Kisslinger

Using the light-front quark model, we calculate the transition form factors, decay rates, and longitudinal lepton polarization asymmetries for the exclusive rare $B\to K\ell^+\ell^…

Frame Dependence of Spin-One Angular Conditions in Light Front Dynamics

B. L. G. Bakker, C. -R. Ji

We elaborate the frame dependence of the angular conditions for spin-1 form factors. An extra angular condition is found in addition to the usual angular condition relating the fou…

Exploring timelike exclusive processes in the light-front approach

Chueng-Ryong Ji, Ho-Meoyng Choi

We discuss a necessary nonvalence contribution in timelike exclusive processes. Utilizing a Schwinger-Dyson type of approach, we relate the nonvalence contribution to an ordinary l…

Poincare Invariant Algebra From Instant to Light-Front Quantization

Chueng-Ryong Ji, Chad Mitchell

We present the Poincare algebra interpolating between instant and light-front time quantizations. The angular momentum operators satisfying SU(2) algebra are constructed in an arbi…

Nonperturbative Vacuum Effect in the Quantum Field Theory of Meson Mixing

Chueng-Ryong Ji, Yuriy Mishchenko

Replacing the perturbative vacuum by the nonperturbative vacuum, we extend a recent development of a quantum field theoretic framework for scalar and pseudoscalar meson mixing. The…

Perturbative QCD and factorization of coherent pion photoproduction on the deuteron

S. J. Brodsky, J. R. Hiller, Chueng-Ryong Ji +1

We analyze the predictions of perturbative QCD for pion photoproduction on the deuteron, gamma D -> pi^0 D, at large momentum transfer using the reduced amplitude formalism. The cl…

New Progress in Time-Like 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…

Skewed quark distribution of the pion in the light-front quark model

Ho-Meoyng Choi, Chueng-Ryong Ji, L. S. Kisslinger

We calculate the skewed quark distributions(SQDs) of the pion in the light-front quark model, and discuss the calculation of the nonvalence contribution to the SQDs in this model.…

K_{l3} transition form factors

Chueng-Ryong Ji, Pieter Maris

The rainbow truncation of the quark Dyson-Schwinger equation is combined with the ladder Bethe-Salpeter equation for the meson bound state amplitudes and the dressed quark-W vertex…

Pion Form Factor and Quark Mass Evolution in a Light-Front Bethe-Salpeter Model

L. S. Kisslinger, Ho-Meoyng Choi, Chueng-Ryong Ji

We discuss the soft contribution to the elastic pion form factor with the mass evolution from current to constituent quark being taken into account using a light-front Bethe-Salpet…
