Distribution of mass in galaxy cluster CL0024 and the particle mass of dark matter
Yuriy Mishchenko, Chueng-Ryong Ji
We study in details the distribution of mass in galaxy cluster CL0024+1654 inferred using the method of strong gravitational lensing by Tyson {\it et al.} (1998). We show that a li…
The Canonical Transformation and Duality in the 1+1 dimensional and theory
Chueng-Ryong Ji, Joon-Il Kim, Dong-Pil Min +1
We investigate the self-organizing nature of relativistic quantum field theory in terms of canonical transformation and duality presenting simple but explicit examples of $(ϕ^4)_{1…
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…
Light-front quark model predictions of meson elastic and transition form factors
Chueng-Ryong Ji, Ho-Meoyng Choi
We investigate the electroweak form factors and semileptonic decay rates of mesons using the constituent quark model based on the light-front degrees of freedom. Our results demons…
Hamiltonian renormalization for bound state problem in gluodynamics
Elena Gubankova, Chueng-Ryong Ji, Stephen R. Cotanch
The systematic approach to study bound states in gluodynamics is presented. The method utilizes flow equations together with low-energy phenomenology, that provides the perturbativ…
Renormalized Effective Hamiltonian Approach to QCD
D. G. Robertson, E. S. Swanson, A. P. Szczepaniak +2
Continuing our previous QCD Hamiltonian studies in the gluonic and quark sectors, we describe a new renormalization procedure which generates an effective Hamiltonian. The formulat…
