- Abstract
The production of charged ρ mesons on nuclei and nucleons is investigated in charged current neutrino interactions at moderate energies (〈 E ≈ 10 GeV), using the data obtained with SKAT bubble chamber. No strong nuclear effects are observed in ρ and ρ production. The fractions of charged and neutral pions originating from ρ decays are obtained and compared with higher-energy data. From analysis of the obtained and available data on ρ and K*(892) neutrino production, the strangeness suppression factor is extracted: λ = 0.18 ± 0.03. Estimation is obtained for cross section of coherent ρ neutrino production on nuclei.
