Mixing angles and electromagnetic properties of ground state pseudoscalar and vector meson nonets in the light-cone quark model
Ho-Meoyng Choi, Chueng-Ryong Ji
Both the mass spectra and the wave functions of the light pseudoscalar () and vector() mesons are analyzed within the framework of the light-cone constituent…
Coupled Channel Analysis of S-Wave Pion-Pion and Kaon-Kaon Photoproduction
Chueng-Ryong Ji, Robert Kaminski, Leonard Lesniak +2
We present a coupled channel partial wave analysis of nondiffractive S-wave pi+ pi- and K+ K- photoproduction focusing on the KK threshold. Final state interactions are included. W…
Consistent Analysis of O(α_s) Corrections to Pion Elastic Form Factor
Adam Szczepaniak, Anatoly Radyushkin, Chueng-Ryong Ji
We examine the role of O(α_s) perturbative corrections to the pion elastic form factor F_π(Q^2). We express the quark current three-point function in terms of light cone variables…
Optimal Renormalization Scale and Scheme for Exclusive Processes
S. J. Brodsky, C. -R. Ji, A. Pang +1
We use the BLM method to fix the renormalization scale of the QCD coupling in exclusive hadronic amplitudes such as the pion form factor and the photon-to-pion transition form fact…
