Renormalization-Scale-Invariant PQCD Predictions for R_e+e- and the Bjorken Sum Rule at Next-to-Leading Order
Michael Binger, Chueng-Ryong Ji, David G. Robertson
We discuss application of the physical QCD effective charge , defined via the heavy-quark potential, in perturbative calculations at next-to-leading order. When coupled with t…
Solving the QCD Hamiltonian for bound states
Elena Gubankova, Chueng-Ryong Ji, Stephen R. Cotanch
The systematic approach to study bound states in quantum chromodynamics is presented. The method utilizes nonperturbative flow equations in the confining background, that makes pos…
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…
Exploring Timelike Region of QCD Exclusive Processes in Relativistic Quark Model
Ho-Meoyng Choi, Chueng-Ryong Ji
We investigate the form factors and decay rates of exclusive semileptonic meson decays using the constituent quark model based on the light-front quantization. Our…
Exploring the timelike region for the elastic form factor in the light-front quantization
Ho-Meoyng Choi, Chueng-Ryong Ji
Even though the Drell-Yan-West formulation is the most rigorous and well-established framework to compute the exclusive processes, its utility has been limited only to the spacelik…
Light-Cone Quark Model Analysis of Radially Excited Pseudoscalar and Vector Mesons
Daniel Arndt, Chueng-Ryong Ji
We present a relativistic constituent quark model to analyze the mass spectrum and hadronic properties of radially excited u and d quark sector mesons. Using a simple Gaussian func…
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…
Light-Front Quark Model Analysis of Exclusive Semileptonic Heavy Meson Decays
Ho-Meoyng Choi, Chueng-Ryong Ji
We present the analysis of exclusive semileptonic heavy meson decays using the constituent quark model based on the light-front quantization. Our model is const…
Quantum Field Theory of Meson Mixing
Michael Binger, Chueng-Ryong Ji
We have developed a quantum field theoretic framework for scalar and pseudoscalar meson mixing and oscillations in time. The unitary inequivalence of the Fock space of base (unmixe…
