AbstractThe magnetic dipole transitions between the vector mesons B* (c) and their relevant pseudoscalar mesons B (c) (B (c) , B* (c) , B (c) (2S), B* (c) (2S), B (c) (3S), B* (c) (3S) etc., the binding states of (c (b) over bar) system) of the B (c) family are interesting. The 'hyperfine' splitting due to spin-spin interaction is an important topic for understanding the spin-spin interaction and the spectrum of the the (c (b) over bar) binding system. The knowledge about the magnetic dipole transitions is also very useful for identifying the vector boson B* (c) mesons experimentally, whose masses are just slightly above the masses of their relevant pseudoscalar mesons B (c) . Considering the possibility to observe the vector mesons via the transitions at Z (0) factory and the potential use of the theoretical estimate on the transitions, we fucus our efforts on calculating the magnetic dipole transitions, i.e. a precise calculation of the rates for the transitions such as decays B* (c) -> B (c) gamma and B* (c) -> B (c) e (+) e (-), and particularly work in the Bethe-Salpeter framework. As a typical example, we carefully investigate the dependence of the rate I"(B* (c) -> B (c) gamma) on the mass difference Delta M = M(B*c)-M(B*c).
