Double charmonium productions in electron-positron annihilation using Bethe-Salpeter approach
Hluf Negash, Shashank Bhatnagar
We calculate the double charmonium production cross section within the framework of Bethe-Salpeter Equation in the electron-positron annihilation, at center of mass ene…
Analytical calculations of ground and excited states of unequal mass heavy pseudoscalar and vector mesons mass spectra using Bethe-Salpeter formalism
Hluf Negash, Shashank Bhatnagar
Considering the fact that, a wide range of variation in masses of various states of heavy pseudoscalar and vector mesons can be seen in different models and the experimental data o…
Radiative decay widths of ground and excited states of vector charmonium and bottomonium
