We investigate the pseudoscalar transition form factors of nucleon for quasi-elastic scattering and Delta resonance production in tau-neutrino nucleon scattering via the charged current interactions. Although the pseudoscalar form factors play an important role for the tau production in neutrino-nucleon scattering, these are not known well. In this Letter, we examine their effects in quasi-elastic scattering and Delta resonance production and find that the cross section, Q(2) distribution, and spin polarization of the produced tau(+/-) leptons are quite sensitive to the pseudoscalar form factors.
