The four-pion final state in pp annihilations at 57 GeV/c

577 events from pp to 2 pi /sup +/2 pi /sup -/ annihilations at 5.7 Ge V/c are analysed. Single particle spectra are studied and effective matrix element is determined. The rates for production of rho degrees and f/sup 0/ mesons are estimated and the influence of resonances on the angular distributi...

Descripción
Sumario:577 events from pp to 2 pi /sup +/2 pi /sup -/ annihilations at 5.7 Ge V/c are analysed. Single particle spectra are studied and effective matrix element is determined. The rates for production of rho degrees and f/sup 0/ mesons are estimated and the influence of resonances on the angular distributions of pions and dipions is investigated. Transverse momenta correlations can be explained using peripheral phase space. (17 refs).
