摘要：

The strong and electromagnetic decays of X(4350) with quantum numbers J(P) = 0(++) and 2(++) have been studied by using the effective Lagrangian approach. The coupling constant between X(4350) and D*(s) D*(s0) is determined with the help of the compositeness condition which means that X(4350) is a bound state of D*D-s*(s0). Other coupling constants applied in the calculation are determined phenomenologically. Our numerical results show that, using the present data, the possibility that X(4350) is a D*D-s*(s0) molecule cannot be ruled out within the present model.
