Abstract
The processes e+e−→K0SK±π∓π0 and e+e−→K0SK±π∓η 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(Kπ)0, K∗(892)±(Kπ)∓, and K0SK±ρ∓ are studied. The J/ψ is observed in all of these channels, and corresponding branching fractions are measured.| File | Dimensione | Formato | |
