s-Channel Profile Factor Model for Regge-ρ Exchange and Duality in π−p → π−Δ+(1236) and π+p → π0Δ++ (1236)

Abstract

We present the results of an analysis of differential cross sections and isobar density matrix elements in isobar production π−p → π−Δ+ (1236) and π+p → π0Δ++ (1236) using an s-channel profile factor model for Regge-ρ exchange previously tested in π−p → π0n. Implications for future experiments are discussed.
