The joint decay distribution statistical tensors for the reaction π + p→ ϱ 0 Δ ++ have been measured as a function of t at 3.75 GeV/ c . From this data the amplitude components of the reaction were extracted using both t -independent and t -independent methods. The magnitudes of the amplitudes obtained from both methods are found to agree and appear to be insensitive to the fitting methods. The phases are not well determined in the t -independent method. A comparison is made with a similar analysis done at 7.1 GeV/c.

The joint decay density-matrix elements have been measured for the ρ0Δ++ and ωΔ++ channels at 3.7 GeV/c. The data are presented as a function of momentum transfer in both the t-channel and s-channel coordinate systems. The presence of correlated decays is illustrated for both reactions by employing selective cuts on the decay angles of one resonance, and displaying the effects on the decay distribution of the opposing resonance. An amplitude analysis is performed with the data near 0° production angle, where we obtain a helicity decomposition of the scattering amplitude with no experimental ambiguity.
