PWA with full rank density matrix of the π+π−π− and π−π0π0 systems at VES setup

Abstract

Partial Wave Analysis of the π+π−π− and π−π0π0 final states produced by 29GeV/c π− beam on beryllium target is presented. About 42 · 106 events for the first system and 22 · 106 events for the second one are collected with VES setup. The statistics for 3π neutral is known to be the largest in the world while statistics for 3π charged is next to largest. The t′ range for the analysis is 0 < |t′| < 0.8 GeV2/c2. The data are analysed using formalism of full rank density matrix. The comparison of the analysis results for two systems is presented.
