Neutrino-induced forward meson-production reactions in nucleon resonance region

Abstract

As a first step toward developing a reaction model that enables a comprehensive description of neutrino-nucleon reactions in the nucleon resonance region, we have applied for the first time a dynamical coupled-channels model, which successfully describes πN, γN --> πN, ηN, ππN, KΛ, KΣreactions up to W = 2 GeV, to predict the neutrino-induced meson-production reactions with ΔS = 0 at the forward angle limit. This has been achieved by relating the divergence of the axial-current matrix elements at Q^2 = 0 to the πN --> X reaction amplitudes through the PCAC hypothesis. We present the contributions from each of the πN, ηN, ππN, KΛ, KΣchannels to the F_2 structure function at Q^2 --> 0 limit up to W = 2 GeV.
