Neutrino induced meson productions in forward limit

Abstract

We study neutrino-induced meson productions off the nucleon in the forward limit by applying the PCAC hypothesis to our dynamical coupled-channels (DCC) model. The DCC model reasonably describes pi N, gamma N -> pi N, eta N, K Lambda, K Sigma data in the resonance region. We give a prediction for nu N -> pi N, pi pi N, eta N, K Lambda, K Sigma$ reactions cross sections. We compare our results with those from the Rein-Sehgal model, and find a significant difference.
