Analysis of the electromagnetic form factors and the radiative decays of the vector heavy-light mesons
In this article, we analyze the electromagnetic form factors of the vector heavy-light mesons to the pseudoscalar heavy-light mesons in the framework of three-point QCD sum rules, where the contributions of vacuum condensate terms 〈q‾q〉, 〈q‾gsσGq〉, 〈gs2G2〉, 〈f3G3〉 and 〈q‾q〉〈gs2G2〉 are considered.

| description | In this article, we analyze the electromagnetic form factors of the vector heavy-light mesons to the pseudoscalar heavy-light mesons in the framework of three-point QCD sum rules, where the contributions of vacuum condensate terms 〈q‾q〉, 〈q‾gsσGq〉, 〈gs2G2〉, 〈f3G3〉 and 〈q‾q〉〈gs2G2〉 are considered. With these results, we also obtain the radiative decay widths of the vector heavy-light mesons and then compare our results with those of other collaboration's. The final results about the radiative decay widths are Γ(D⁎0→D0γ)=1.74−0.37+0.40 keV, Γ(D⁎+→D+γ)=0.17−0.07+0.08 keV, Γ(Ds⁎→Dsγ)=0.029−0.008+0.009 keV, Γ(B⁎0→B0γ)=0.018−0.005+0.006 keV, Γ(B⁎+→B+γ)=0.015−0.007+0.007 keV and Γ(Bs⁎→Bsγ)=0.016−0.005+0.003 keV. |
