Abstract
By using a generalized relativistic quark pair creation model (QPCM), the hadronic decay processes of ψ(4030), assigned as the 3S state of , are investigated. The relative rates of ,and in particular are calculated and compared with data. The nodes of the radially excited wavefunctions of charmonium states are found to be significant for these decay processes. Considering the SU(3) suppression factor of ~ 3 for the s quark pair creation relative to the u and d quarks, we obtain nb.
