Abstract
The processes e+e-âKS0KÂ±Ï Ï0 and e+e-âKS0KÂ±Ï Î· 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 Kâ0(KÏ)0, Kâ(892)±(KÏ) , and KS0KÂ±Ï are studied. The J/Ï is observed in all of these channels, and corresponding branching fractions are measured.File in questo prodotto:
