Abstract

Results are presented of a study of ϱ-ω interference effects in high statistics, good resolution, πp → π+πn data obtained at 17.2 GeV using the CERN-Munich spectrometer. We investigate the t dependence of ϱ-ω interference in the various ππ production amplitudes. While effects are observed in all the P-wave production amplitudes, the most pronounced structure occurs in the natural parity exchange amplitude in the t interval 0.1 ⩽ −t ⩽ 0.4 GeV2. Under certain assumptions we determine the relative magnitudes and phases of the ϱ- and ω-production amplitudes as functions of t.
