Description

The reaction π+p → rho0Δ++(1236) at 16 GeV/c has been studied. Cross section, differential cross section, single and joint spin-density matrix elements are given. Correlations between the rho0 and Δ++(1236) decay distributions are observed. Unnatural spin-parity exchanges, mainly observed at small t' values, dominate the rho0Δ++(1236) production. The natural exchange contributions are only (7+-2)% and become as important as the unnatural exchanges beyond t' = 0.3 GeV2. Contributions to Δ++(1236) - helicity 3/2 states do not exceed 20% of the total rho0Δ++(1236) cross section and are mainly due to unnatural exchanges. (author)
