In this paper we have calculated transition magnetic moments and radiative decay widths of light and heavy mesons using a relativistic potential model of independent quarks with its parameters determined from a fit to the mass of ground state mesons in the strange, charm and bottom flavor sectors. The results are in agreement with the experimental data.

The decay widths for M1 transitions of mesons are calculated in a relativistic potential model of independent quarks with its parameters determined from a fit to the mass splittings of the ground state mesons in the strange, charm and bottom flavor sector. A more realistic calculation of the decay widths is performed beyond static approximation incorporating some momentum dependence due to recoil of the daughter meson. The model accounts well for the observed decay widths of light mesons and predicts decay rates of heavy mesons which are comparable with those of other model calculations.

We calculated the mass spectra of charmonium meson by using matrix method to make the predictions of ground and radially excited states of charmonium mesons via non-relativistic potential model. We compared our results with other theoretical approaches and recently published experimental data. The predictions are found to be in a good accordance with the latest experimental results of Particle data group and with the results of other theoretical approaches. Besides, we calculated the momentum width coefficients β of charmonium meson. Since, there are no experimental data for the momentum width coefficients β of charmonium meson yet. Consequently, our calculated coefficients β are compared with other theoretical studies and it is found to be in a good agreement with our results. The obtained results of coefficients β have implications for decay constants, decay widths and differential cross sections for charmonium system and generally for heavy mesons system. Our study is considered as theoretical calculation of some properties of charmonium meson.

Radial Wave Equation

In this paper, a non-relativistic potential model is used to find the solution of radial Schrodinger wave equation by using Crank Nicolson discretization for heavy quarkonia ( ̅, ̅). After solving the Schrodinger radial wave equation, the mass spectrum and hyperfine splitting of heavy quarkonia are calculated with and without relativistic corrections. The root means square radii and decay constants for S and P states of c ̅ and ̅ mesons by using the realistic and simple harmonic oscillator wave functions. The calculated results of mass, hyperfine splitting, root means square radii and decay constants agreed with experimental and theoretically calculated results in the literature.
