Description

In this work, we study the radiative open-charm decays Y(4140)→Ds*+Ds-γ and Y(3930)→D*+D-γ under the assignments of Ds*Ds* and D*D* as molecular states for Y(4140) and Y(3930), respectively. Based on our numerical result, we propose the experimental measurement of the photon spectrum of Y(4140)→Ds*+Ds-γ, Ds+Ds*-γ and Y(3930)→D*0D0γ, D0D*0γ, D*+D-γ, D+D*-γ can further test the molecular assignment for Y(4140) and Y(3930).
