Dynamical Model of Electroweak Pion Production Reaction

Abstract

The dynamical model of pion electroproduction developed by the authors has been extended to study the pion weak production reaction. The axial vector N-Delta transition form factor G_A^{NΔ} obtained from the analysis of existing neutrino reaction data and the role of dynamical pion cloud on G_A^{NΔ} are discussed.
