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 γn→p π + π − π − and γn→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 γn→ ΛK + π −, Σ −K 0 π +, pK −K 0, ΛK 0 π + π − and ΛK + π − π 0 are presented. Production of Σ −(1385) and K ∗0(890) was observed.
