Electromagnetic transitions between two mesons containing different masses of heavy quarks using BS framework

Abstract

In this paper, we calculate the electromagnetic (EM) transition decay widths between two mesons containing different heavy quarks (c and b) for the process; [Formula: see text], using the Bethe–Salpeter (BS) framework. The calculated results are found to be in a reasonable agreement with other theoretical models but the experimental data for this problem is not yet available.
