Radiative decays of heavy-light quarkonia through , and transitions in the framework of Bethe-Salpeter equation
Shashank Bhatnagar, Eshete Gebrehana
In this work we study the radiative decays of heavy-light quarkonia through M1 and E1 transitions, that involve quark-triangle diagrams with two hadron vertices, and are difficult…
