摘要：

The production of charged rho mesons on nuclei and nucleons is investigated in charged current neutrino interactions at moderate energies (aEuroE (aEuro parts per thousand) a parts per thousand 10 GeV), using the data obtained with SKAT bubble chamber. No strong nuclear effects are observed in rho (+) and rho (-) production. The fractions of charged and neutral pions originating from rho decays are obtained and compared with higher-energy data. From analysis of the obtained and available data on rho (+) and K*(+)(892) neutrino production, the strangeness suppression factor is extracted: lambda (s) = 0.18 +/- 0.03. Estimation is obtained for cross section of coherent rho (+) neutrino production on nuclei.
