Abstract：
In my talk, we present the dynamical study of Y(4140) and Y(3930) under the D_s^*D_s^* and D^*D^* molecular assignments respectively. The importance to theoretically and experimentally study their open-charm decay, hidden-charm decay, radiative decay and double-photon decay is proposed combing with the theoretical calculation of the decay behavior of Y(4140) and Y(3930). According to the recent new experimental progress made by Belle, we further indicate the reasonability of molecular explanation to Y(4140). Another event cluster around 4270 MeV in the J/ψφ invariant mass spectrum of B→K J/ψφ can provide us more hints to reveal the creation mechanism of molecular structure in B meson decay, which will be helpful to clarify the underlying structure of Y(4140) and Y(3930).
