Abstract

The analysis of the mass spectrum and the calculation of the strong decay of P-wave charmonium states strongly support to explain the newly observed X(3915) and X(4350) as new members in P-wave charmonium family, i.e., χ_c0^′ for X(3915) and χ_c2^′′ for X(4350). Under the P-wave charmonium assignment to X(3915) and X(4350), the J^PC quantum numbers of X(3915) and X(4350) must be 0⁺⁺ and 2⁺⁺ respectively, which provide the important criterion to test P-wave charmonium explanation for X(3915) and X(4350) proposed by this letter. The decay behavior of the remaining two P-wave charmonium states with the second radial excitation is predicted, and experimental search for them is suggested.
