Recent results on coherent and incoherent particle production in ν-nucleus interactions below 30 GeV

The coherent pion production reactions, inclusive strange particle production and cumulative proton production reactions are presented. The data come from an exposure of the heavy freon filled bubble chamber SKAT to the wide band (anti)neutrino beam of the Serpukhov 70 GeV proton accelerator. All three possible coherent pion production channels of weak charged and neutral current interactions in one experiment are analysed. From the inclusive strange particle reaction the total strange and charm particle cross section in the unexplores low energy region near the production threshold is calculated. For cumulative protons experimental hints that this process is due to secondary interactions in the nucleus instead of scattering on nuclear clusters is found. 16 refs., 13 figs. (M.F.W.)
