Multipion and strange particle photoproduction off neutrons up to 5.3 GeV

Abstract In a study of photoproduction at photon energies up to 5.3 GeV in a deuterium bubble chamber the reactions γ n→p π + π − π − and γ n→p π + π − π − π 0 were analyzed. In these reactions production of the resonances Δ ++ , Δ 0 , ϱ 0 , ω and A 2 − was observed. Photoproduction of strange particles was investigated and cross sections for the reactions γ n→ Λ K + π − , Σ − K 0 π + , pK − K 0 , Λ K 0 π + π − and Λ K + π − π 0 are presented. Production of Σ − (1385) and K ∗0 (890) was observed.
