The yields of light meson resonances in neutrinonuclear interactions at <E_nu> = 10 GeV

Abstract

The total yields of the all well-established light mesonic resonances (up to the $\phi$(1020) meson) are estimated in neutrinonuclear interactions at < E_nu > = 10 GeV, using the data obtained with SKAT bubble chamber. For some resonances, the yields in the forward and backward hemispheres in the hadronic c.m.s. are also extracted. From the comparison of the obtained and available higher-energy data, an indication is obtained that the resonance yields rise almost linearly as a function of the mean mass < W > of the neutrinoproduced hadronic system. The fractions of pions originating from the light resonance decays are inferred.
