英文摘要: Using the general form of the Bethe-Salpeter wave functions for the bound states consisting of two vector fields given in our previous work, we investigate the molecular state composed of D-s*(+) D-s*(-). However, for the SU(3) symmetry the component D-s*(+) D-s*(-) is coupled with the other components D*(0)(D) over bar*(0) and D*(+) D*(-). Then we interpret the internal structure of the observed Y(4140) state as a mixed state of pure molecule states D*(0)(D) over bar*(0), D*(+) D*(-) and D-s*(+) D-s*(-) with quantum numbers J(P) = 0(+). In this paper, the operator product expansion is used to introduce the nonperturbative contribution from the vacuum condensates into the interaction between two heavy mesons. The calculated mass of Y (4140) is consistent with the experimental value, and we conclude that it is a more reasonable scenario to explain the structure of Y (4140) as a mixture of pure molecule states.
