Abstract: (Elsevier)
By analyzing the data sets of 17.3 pb −1 taken at s=3.773 GeV and of 6.5 pb −1 taken at s=3.650 GeV with the BES-II detector at the BEPC collider, we measure the observed cross sections for the exclusive light hadron final states of KS0K−π+ , KS0K−π+π0 , KS0K−π+π+π− , KS0K−π+π+π−π0 , KS0K−π+π+π+π−π− and KS0K−π+π0π0 produced in e+e− annihilation at the two energy points. We set the upper limits on the observed cross sections and the branching fractions for ψ(3770) decay to these final states at 90% C.L.Note:
