Observation of the production of charmed *++c baryons in neutrino interactions at the SKAT bubble chamber
Quasielastic production of charmed baryons at protons has been studied with the SKAT bubble chamber, exposed to a neutrino beam at the Serpukhov U-70 accelerator. The results are reported. The first observation of a 2C* + + baryon, with a mass Af(2?+ + ) =2.530±0.005±0.005 GeV, is reported. Estimates are found for some reaction cross sections: σ(ν/?-*μ~Σίι~ + ) = (2.3±2.0)XlO-40cm2 and σ(ν/>-μ~Σ*+ + ) = (4.5±4.0) Χ 10"40 cm2.
