Query: Weak charged and neutral current induced one pion production off the
  nucleon   We present a study of neutrino/antineutrino induced charged and neutral
current single pion production off the nucleon. For this, we have considered
$P_{33}(1232)$ resonance, non-resonant background terms, other higher
resonances like $P_{11}(1440)$, $S_{11}(1535)$, $D_{13}(1520)$, $S_{11}(1650)$
and $P_{13}(1720)$. For the non-resonant background terms a microscopic
approach based on SU(2) non-linear 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 $C_5^{A}(0)$ in the case of $P_{33}(1232)$ resonance is
obtained by fitting the ANL and BNL $\nu$-deuteron reanalyzed scattering data.
The results are presented with and without deuteron effect for the total
scattering cross sections for all possible channels viz.
$\nu_l(\bar\nu_l)~+~N\rightarrow l^-(l^+)~+~N^\prime~+~\pi^i$;
$\nu_l(\bar\nu_l)~+~N\rightarrow \nu_l(\bar\nu_l)~+~N^\prime~+~\pi^i$, where
$N, N^\prime=p,n$, $\pi^i=~\pi^\pm$ or $\pi^0$ and $l=e, \mu$.
