The quasielastic production cross sections and polarizations of the hyperons induced by 
on the free nucleon as well as from 
Ar in the sub-GeV energy region has been reviewed (Fatima et al., Front Phys 7:13, 2019; Fatima et al., Phys Rev D 98:033005, 2018; Akbar et al., Phys Rev D 94:114031, 2016; Fatima et al., Eur Phys J A 54:95, 2018; Akbar et al., Eur Phys J A 53:154, 2017). The effects of the second class currents in the axial vector sector with and without T-invariance as well as the effect of SU(3) symmetry breaking are also studied. We find that the cross sections and the various polarization components can effectively be used to determine the axial vector transition form factors in the strangeness sector and to test the validity of various symmetries of the weak hadronic currents like G-invariance, T-invariance and SU(3) symmetry. These hyperons decay dominantly into pions giving an additional contribution to the weak pion production induced by the antineutrinos. In the case of nuclear targets like Ar, this contribution is shown to be significant when compared with the pion production by the 
excitations in the energy range of 
GeV (Fatima et al., Front Phys 7:13, 2019). This study could be useful for the DUNE experiment where argon will be used as the target material and the electronic imaging of particles is possible and the particle tracks can be identified.
