Nearly 40000 neutrino and antineutrino interactions in BEBC are compared to measure the differences between neon and deuterium in the quark and antiquark distributions and in the nucleon structure functions. The ratio of Ne to D cross sections indicates some decrease betweenx∼0.2 andx∼0.6. They distributions show there is no significant increase in the neon sea, but prefer a small decrease. Taken altogether, thex andy distributions and the measured total cross-sections indicate some change in the shape of the valence distributions. No significant dependence onA is observed for either the shape of the sea or the ratio of longitudinal to transverse cross-sections.

Observation of $\mu^- e^-$ Events in Neutrino Interactions at 3-{GeV} to 30-{GeV}

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

Ammosov, V.V. ; Ivanilov, A.A. ; Ivanov, P.V. ; et al.

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.
