摘要
The processes e(+) e(-) -> (KsK +/-)-K-0 pi(-/+)pi(0) and e(+) e(-) -> K-s(0) K-+/-pi(-/+)eta are studied over a continuum of energies from threshold to 4 GeV with the initial-state photon radiation method. Using 454 fb(-1) of data collected with the BABAR detector at the SLAC PEP-II storage ring, the first measurements of the cross sections for these processes are obtained. The intermediate resonance structures from K-*0(K pi)(0), K*(892)(+/-)(K pi)(T),and (KsK +/-)-K-0 rho(-/+)are studied. The J/psi is observed in all of these channels, and corresponding branching fractions are measured.
