We present a study of neutrino/antineutrino induced charged current (CC) and neutral current (NC) single pion production (SPP) off the nucleon. For this, we have considered [Formula: see text] resonance, nonresonant background (NRB) terms, other higher resonances like [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text]. For the NRB terms a microscopic approach based on [Formula: see text] nonlinear sigma model has been used. The vector form factors for the resonances are obtained by using the relationship between the electromagnetic resonance form factors and helicity amplitudes provided by MAID. Axial coupling [Formula: see text] in the case of [Formula: see text] resonance is obtained by fitting the ANL and BNL [Formula: see text]-deuteron reanalyzed scattering data. The results are presented with and without deuteron effect for the total scattering cross-sections for all possible channels, viz. [Formula: see text] and [Formula: see text], where [Formula: see text], [Formula: see text] or [Formula: see text] and [Formula: see text].
