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...
