Description

Numerical recovering of the spectrum and wave function of a two-body fermionic relativistic potential system.
Estimation in this framework of the widths and branching ratios of some heavy mesons radiative decays.

Summary

In previous work we presented a unified two-fermion covariant model which predicted a very good spectrum for the masses of light and heavy mesons.
By utilising the same model we here analyse the available measured radiative decays of Υ(3s),χb2(2p),χb1(2p),χb0(2p),Υ(2s) and we calculate their branching ratios and their widths.
The values obtained with this method are in a good agreement with the experimental data.
