摘要：
Taking D*(S0) (2317)(+) as a conventional c (s) over bar meson, we calculate its dominant strong and electromagnetic decays in the framework of the Bethe-Salpeter method. Our results are Gamma(D*(s0) -> D-s(+) pi(0)) = 7.83(-1.55)(+1.97) keV and Gamma(D*(+)(s0) -> D*(+)(s) gamma) = 2.55(-0.45)(+0.37) keV. The contributions of the different partial waves from the initial and final state wave functions to the decay width are also calculated, and we find that the relativistic corrections in both decay processes are very large.
