Chirally symmetric quark description of low energy π-πscattering
Pedro Bicudo, Stephen Cotanch, Felipe Llanes-Estrada +3
Weinberg's theorem for π-πscattering, including the Adler zero at threshold in the chiral limit, is analytically proved for microscopic quark models that preserve chiral symmetry.…
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…
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…
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.…
Relativistic Many-Body Hamiltonian Approach to Mesons
Felipe J. Llanes-Estrada, Stephen R. Cotanch
We represent QCD at the hadronic scale by means of an effective Hamiltonian, , formulated in the Coulomb gauge. As in the Nambu-Jona-Lasinio model, chiral symmetry is explicity…
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…
