Abstract
We study the processes e+e− → K+K−π0π0π0γ, K0SK+-π∓π0π0γ, and K0SK+-π∓πþπ−γ in which an energetic photon is radiated from the initial state. The data were collected with the BABAR detector at the SLAC National Accelerator Laboratory. About 1200, 2600, and 6000 events, respectively, are selected from a data sample corresponding to an integrated luminosity of 469 fb−1. The invariant mass of the hadronic final state defines the effective e+e− center-of-mass energy. The center-of-mass energies range from threshold to 4.5 GeV. From the mass spectra, the first ever measurements of the eþe− → KþK−π0π0π0, eþe− → K0SK+-π∓π0π0, and e+e− → K0SK+-π∓πþπ− cross sections are performed.| File | Dimensione | Formato | |
