Abstract
A detailed analysis is presented of about 6000 events belonging to the final states p2 π +3 π −, p2 π +3 π − π 0 and n3 π +3 π − produced in π −p interactions at 3.93 GeV/ c. The main features of the data are found to be well approximated by the predictions of relativistic phase-space, in spite of copious resonance production amounting to approximately 80% of the cross section. The resonance fractions are estimated from a maximum likelihood fit to the data using a phenomenological model describing the peripheral production of resonances and the symmetrization of the wave-function with respect to identical pions. A study is also made of two pion correlations.
