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.

Study of the Reaction anti-p p --> anti-Delta++ Delta++ at 9.1-GeV/c

Walck, C. ; Carlsson, R. ; Ekspong, G. ; et al.

Single and joint decay angular distributions in the reaction p p → Δ ++ Δ ++ at 9.13 GeV/ c are discussed in the framework of single and double statistical tensors. The t dependence of 12 double statistical tensors is presented. Cross sections for p p → p p π + π − and p p → Δ ++ Δ ++ are determined to be 2.60 ± 0.10 and 0.90 ± 0.10 mb respectively. The results obtained are compared with other experiments mainly at 5.7 and 12 GeV/ c .
