Abstract Evidence is presented for diffractive production of ρ-mesons and of ρπ-systems invp and $$\bar \nu p$$ chargedcurrent interactions. In the (anti-)neutrino energy range 10 GeV〈E v 〈60 GeV the cross sections for diffractive ρ and diffractive ρπ production are found to be (0.64±0.14 (stat.)±0.08 (syst.))% and (0.28±0.08 (stat.)±0.04 (syst.))% of the charged-current cross section. The diffractive ρπ signal is consistent with being entirely due to diffractivea 1 production. However, the data cannot distinguish between diffractivea 1 and diffractive nonresonant ρπ production. The experimental distributions ofW, Q 2,x Bj andy Bj for diffractive ρ and ρπ events are consistent with model predictions.
