Calculation of magnetic dipole decay widths between two mesons containing two different heavy quarks within the framework of BS approach

Academic Paper from the year 2020 in the subject Physics - Other, , language: English, abstract: In this paper, we calculated the magnetic decay widths between two mesons containing two different heavy quarks ($coverline{b}$) for the process of $B^{*}_{c}rightarrow B_{c}+gamma$, within the framework of Bethe-Salpeter approach. The calculated values are found to be in a reasonable agreement with other theoretical results.
