主　　题：D^(s)(2317) relativistic Bethe-Salpeter equation 

摘      要：Taking D^(*)_(s0)(2317)^(+)as a conventional cs meson,we calculate its dominant strong and electromagnetic decays in the framework of the Bethe-Salpeter *** results areΓ(D^(∗+)_(s0)→D^(+)_(s)π^(0))=7.83^(+1.97)_(-1.55)keV andΓ(D^(∗+)_(s0)→D^(∗+)_(s)γ)=2.55^(+0.37)_(-0.45)*** 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.
