Study of Δ++ production in π-p interactions at 100, 200, and 360 GeV/c


Journal Article

We present a systematic study of Δ++ production in π-p reactions at Fermilab energies. Inclusive and semi-inclusive Δ++(1232) production cross sections are determined. We observe these cross sections to be energy independent. The invariant cross sections as a function of Feynman x and pT2 are also energy independent consistent with scaling behavior. We show that Δ++ production is consistent with a one-pion-exchange mechanism. Comparison of the density matrix elements with model predictions and results of a triple-Regge analysis both support the validity of a one-pion-exchange model. © 1979 The American Physical Society.
