Investigating the parity of the exotic Theta^+ baryon from the kaon photoproduction
Byung Geel Yu, Tae Keun Choi, Chueng-Ryong Ji
Based on the hadronic model with the gauge prescription suggested by Ohta and Haberzettl, we investigate the possibility of determining the parity state of the baryon using p…
Radiative Scalar Meson Decays in the Light-Front Quark Model
Martin A. DeWitt, Ho-Meoyng Choi, Chueng-Ryong Ji
We construct a relativistic wavefunction for scalar mesons within the framework of light-front quark model(LFQM). This scalar wavefunction is used to perform relativistic c…
Transition Form Factors between Pseudoscalar and Vector Mesons in Light-Front Dynamics
Bernard L. G. Bakker, Ho-Meoyng Choi, Chueng-Ryong Ji
We study the transition form factors between pseudoscalar and vector mesons using a covariant fermion field theory model in dimensions. Performing the light-front calculati…
Angular Conditions,Relations between Breit and Light-Front Frames, and Subleading Power Corrections
Carl E. Carlson, Chueng-Ryong Ji
We analyze the current matrix elements in the general collinear (Breit) frames and find the relation between the ordinary (or canonical) helicity amplitudes and the light-front hel…
Molar mass estimate of dark matter from the dark mass distribution measurements
Yuriy Mishchenko, Chueng-Ryong Ji
We study the distribution of dark matter versus visible matter using a set of data obtained from strong gravitational lensing in the galaxy cluster CL0024+1654 and another set of d…
