|Charged ρ Meson Production in Neutrino Induced Reactions at 〈Eν 〉 ≈ 10 GeV|
|Protvino, 2010. – p. 12, figs.: 6, tables 2, refs.: 21.|
The production of charged ρ mesons on nuclei and nucleons is investigated in charged current neutrino interactions at moderate energies (〈Eν 〉 ≈ 10 GeV), using the date 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: λs = 0.18± 0.03. Estimation is obtained for cross section of coherent ρ+ neutrino production on nuclei.
