Abstract:Using the data obtained with the SKAT bubble chamber, the total yields of K*(892)+, Σ+(1385), and Σ0 are estimated for the first time in neutrino-induced reactions at moderate energy 〈E v〉 = 10.4 GeV. It is shown that the recently observed enhancement of the K 0 and Λ yields in vA interactions as compared to vN interactions is contributed only slightly by the K*(892)+ and Σ+(1385) production. The contribution of resonances to the K 0 and Λ yields is found to be in qualitative agreement with higher energy (〈E v〉 ≳ 40 GeV) data. It is shown that the energy dependence of the K*(892)+ mean multiplicity in vN interactions is approximately linear in the range of 〈E v〉 ≈ 10−60 GeV, while that for Σ0 in vA interactions (A = 20−21) is approximately logarithmic in the range of 〈E v〉 ≈ = 10−150 GeV. The text was submitted by the authors in English.
