A novel variational approach for Quantum Field Theory: example of study of the ground state and phase transition in Nonlinear Sigma Model
Yuriy Mishchenko, Chueng-Ryong Ji
We discuss a novel form of the variational approach in Quantum Field Theory in which the trial quantum configuration is represented directly in terms of relevant expectation values…
Possibility of determinig the parity of the pentaquark from photoproduction near threshold
Byung Geel Yu, Tae Keun Choi, Chueng-Ryong Ji
We discuss the possibility of determining the parity of the baryon from photoproduction process near threshold. We utilize the conservation laws of parity and an…
Phenomenology of flavor oscillations with non-perturbative effects from quantum field theory
Antonio Capolupo, Chueng-Ryong Ji, Yuriy Mishchenko +1
We analyze phenomenological aspects of the quantum field theoretical formulation of meson mixing and obtain the exact oscillation formula in the presence of the decay. This formula…
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…
Time-to-space conversion in quantum field theory of flavor mixing
Chueng-Ryong Ji, Yuriy Mishchenko
We consider the problem of time-to-space conversion in quantum field theory of flavor mixing using a generalization of the wave-packet method in quantum mechanics. We work entirely…
Electromagnetic Structure of the Meson in the Light-Front Quark Model
Ho-Meoyng Choi, Chueng-Ryong Ji
We investigate the elastic form factors of the rho meson in the light-front quark model(LFQM). With the phenomenologically accessible meson vertices including the one obtained by t…
