In this paper, we calculated the magnetic decay widths between two mesons containing two different heavy quarks ($c\overline{b}$) 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.

This paper aims to calculate the magnetic decay widths between two mesons containing two different heavy quarks (cb) for the process of B* → Bc+y, within the framework of the Bethe-Salpeter approach. The study aims to contribute to the understanding of bound states of heavy quark and anti-quark systems and the non-perturbative regime of QCD.

Zusammenfassung der Kapitel (Chapter Summaries)
- Introduction: This section provides background on the study of heavy mesons and the importance of understanding their mass spectrum and decay transitions. It introduces the Bethe-Salpeter equation (BSE) as a successful approach for dealing with relativistic bound state problems in QCD and highlights the significance of heavy meson decays for investigating the nature of inter-quark forces and decay mechanisms. It also outlines the previous work done by the authors using the BSE framework to calculate mass spectra and transition amplitudes for various processes involving heavy mesons.
- Calculation of decay widths between two mesons: This section presents the mathematical expressions and numerical calculation of the magnetic dipole decay widths for the process B* → Bc+y. It explains the Feynman diagrams involved in the transition process, defines the relevant momentum relations, and derives the expression for the transition amplitude in terms of the Bethe-Salpeter wave functions.
