Résumé : The reaction K+p→Δ++(1236)+ anything is studied at beam momenta 8.2 and 16 GeV/c and compared with other Δ++ producing reactions. We find that the low-mass Δ++π- enhancement affects the shapes of Δ++ inclusive distributions. The triple-Regge formula is found to be consistent with the data. Dual properties of this formula are successfully tested. © 1976.
