The joint decay distribution for the reaction pp → Δ++Δ0 is described in terms of double statistical tensors, which were determined in a model-independent way using the World Proton-Proton Data Summary Tape. The statistical tensors were calculated in nontransversal and in transversal reference frames. The results are presented as a function of the proton laboratory momentum, covering the range from 5 to 25 GeV/c. Due to a lack of statistics, the values as a function of the four-momentum transfers were obtained by adding together data from different energies. Results are again given in several reference frames.

A Study of the Reactions pi+ p --> (rho0, omega) Delta++ at 13-GeV/c

Gaidos, J.A. ; Hirata, A.A. ; DeBonte, R.J. ; et al.
Nucl.Phys.B 72 (1974) 253-282, 1974.
Inspire Record 763 DOI 10.17182/hepdata.32316

Cross sections, differential cross sections, density matrix elements and statistical tensors are given for the reactions π + p → ( ϱ 0 , ω ) Δ ++ at 13.2 GeV/ c . A discussion of the results in terms of particle exchanges, quark model or dipole coupling constraints, and the equal phase hypothesis is presented in some detail for the high statistics ϱ 0 Δ ++ channel.
