Estimating strong decays of X(3915) and X(4350)
  Strong decays of X(3915) and X(4350) have been studied by assuming them as P-wave charmonium states. We estimate the {\Gamma}(X(3915) \to J/{\psi}{\omega}) and {\Gamma}(X(4350) \to J/{\psi}\phi) via D(*)D(*)open-charm intermediate states. Our calculation supports that the assignment of X(4350) to the charmonium state while the assignment of X(3915) is disfavored.
