Query: Weak quasielastic hyperon production leading to pions in the
  antineutrino-nucleus reactions   In this review, we have studied the quasielastic production cross sections
and polarization components of $\Lambda$, $\Sigma^0$ and $\Sigma^-$ hyperons
induced by the weak charged currents in the antineutrino reactions on the
nucleon and the nuclear targets like $^{12}$C, $^{16}$O, $^{40}$Ar and
$^{208}$Pb. It is shown that the energy and the $Q^2$ dependence of the cross
sections and the various polarization components can be effectively used to
determine the axial vector transition form factors in the strangeness sector
and test the validity of various symmetry properties of the weak hadronic
currents like G-invariance, T-invariance and SU(3) symmetry. In particular, the
energy and the $Q^2$ dependence of the polarization components of the hyperons
is found to be sensitive enough to determine the presence of the second class
current with or without T-invariance.
  These hyperons decay dominantly into pions giving an additional contribution
to the weak pion production induced by the antineutrinos. This contribution is
shown to be quantitatively significant as compared to the pion production by
the $\Delta$ excitation in the nuclear targets in the sub-GeV energy region
relevant for the $\bar{\nu}_\mu$ cross section measurements in the oscillation
experiments. We have also included a few new results, based on our earlier
works, which are in the kinematic region of the present and future
(anti)neutrino experiments being done with the accelerator (anti)neutrinos at
T2K, MicroBooNE, MiniBooNE, NO$\nu$A, MINER$\nu$A and DUNE, as well as for the
atmospheric (anti)neutrino experiments in this energy region.
