Abstract (data abstract)
SLAC-PEP2. Measurement of the cross sections for 2PI+ 2PI-, K+ K- PI+ PI- and 2K+ 2K- in E+ E- interactions at centre of mass energies from production threshold to 4.5 GeV from data with a photon from the initial state radiation. The data has around 60000 reconstructed events selected from 89 fb-1 data.
