PRODUCTION-RATE OF DS+DS- AT PSI(4030)

By using a generalized relativistic quark pair creation model (QPCM), the hadronic decay processes of psi(4030), assigned as the 3S state of <c(c)over bar>, are investigated. The relative rates of psi(4030)-->< D(D)over bar>, <D(D)over bar>+<(D)over bar D*>, <D*(D)over bar*>, and in particular Ds+Ds- 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) sup pression factor of similar to 3 for the s quark pair creation relative to the u and d quarks, we obtain sigma(e(+)e(-)-->psi(4030)-->Ds+Ds-) similar to 0.9 nb.
