Estimates for X(4350) Decays from the Effective Lagrangian Approach

Abstract

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 $D_s^{\ast }{D}_{s0}^{\ast }$ is determined with the help of the compositeness condition which means that $X(4350)$ is a bound state of $D_s^{\ast }{D}_{s0}^{\ast }$. Other coupling constants applied in the calculation are determined phenomenologically. Our numerical results show that, using the present data within the present model, the possibility that $X(4350)$ is a $D_s^{\ast }{D}_{s0}^{\ast }$ molecule can not be ruled out.
