The contribution of possible intranuclear secondary processes (interactions of secondary mesons with nucleons and few-nucleon systems, interactions of Δ-resonances with nucleons) to cumulative proton production in π − c interactions at 5 GeV/ c is studied. It has been found that the contribution of secondary processes makes nearly half of the inclusive cross section of cumulative proton production at momenta p p ⩽ 0.75 GeV/ c .

The production of μ − e − pairs is studied in interactions of neutrinos with nuclei of heavy freon in the SKAT bubble chamber experiment. A rate of μ − e − pairs to charged current interactions of R μ − e − =(2.5± 1.4 4.3 )×10 −4 is found at an average neutrino energy of 10 GeV. The ratio μ − e − / μ − e + comes out to be μ − e − / μ − e + = 0.12± 0.08 0.22 .

Production of $\mu^- e^+$ Pairs in Neutrino interactions in the SKAT Bubble Chamber Experiment

The production of μe-pairs is studied in interactions of neutrinos with nuclei of heavy freon in the SKAT bubble chamber experiment. A rate of μ−e+ to charged current interactions above the charm threshold of$R^{\mu ^ -e^ +}= (4.6 \pm 1.2) \cdot 10^{ - 3} $ is found. The properties of the observed μ−e+ events can be well described by assuming them to originate from the semileptonic decay of quasielastic produced charmed baryonsΛc and inclusive charmedD-meson production. The rates for these reactions are found to be (6.7±3.5)×10−2 and (2.5±0.9)×10−2, respectively. A total charmed particle production rate of (9.2±3.6)×10−2 is calculated.

We present inclusive ϱ ±,0 and ω cross sections in the beam fragmentation region of π + p interactions at 250 GeV/ c . The near equality of the ϱ + and ϱ 0 cross sections implies suppression of valence quark recombination in forward vector meson production.
