Abstract
We investigate the pseudoscalar transition form factors of nucleon for quasi-elastic scattering and Îresonance production in tau-neutrino nucleon scattering via the charged current interactions. Although the pseudoscalar form factors play an important role for the Ïproduction in neutrino-nucleon scattering, these are not known well. In this article, we examine their effects in quasi-elastic scattering and Îresonance production and find that the cross section, Q^{2} distribution, and spin polarization of the produced Ï^{\pm} leptons are quite sensitive to the pseudoscalar form factors.
