  We present results for the quasi-elastic weak production of $\Lambda$ and
$\Sigma$ hyperons induced by $\bar{\nu}$ scattering off nuclei, in the
kinematical region of interest for accelerator neutrino experiments. We employ
realistic hole spectral functions and we describe the propagation of the
hyperons in the nuclear medium by means of a Monte Carlo cascade. The latter
strongly modifies the kinematics and the relative production rates of the
hyperons, leading to a non-vanishing $\Sigma^+$ cross section, to a sizable
enhancement of the $\Lambda$ production and to a drastic reduction of the
$\Sigma^0$ and $\Sigma^-$ distributions. We also compute the quasi-elastic weak
$\Lambda_c$ production cross section, paying special attention to estimate the
uncertainties induced by the model dependence of the vacuum $n\to \Lambda_c$
weak matrix element. In this regard, the recent BESIII measurements of the
branching ratios of $\Lambda_c\rightarrow \Lambda l^+\nu_l$ ($l=e,\mu$) are
used to benchmark the available theoretical predictions.
