1. Double Charmonium Productions in Electron-Positron Annihilation Using Bethe-Salpeter Approach / Negash, Hluf ; Bhatnagar, Shashank ; Bhatnagar, Shashank
We calculate the double charmonium production cross-section within the framework of 4×4 Bethe-Salpeter Equation in the electron-positron annihilation, at center of mass energy s=10.6 GeV, that proceeds through the exchange of a single virtual photon. [...]

2. Radiative Decay Widths of Ground and Excited States of Vector Charmonium and Bottomonium / Negash, Hluf ; Bhatnagar, Shashank
We study the radiative decay widths of vector quarkonia for the process of J/ψ(nS)ηc(nS)γ and Υ(nS)ηb(nS)γ (for principal quantum numbers n=1,2,3 ) in the framework of Bethe-Salpeter equation under the covariant instantaneous ansatz using a 4×4 form of BSE. [...]
