In this work we study the $\Sigma\pi$ and $\Lambda\pi$ production off free nucleons driven by the strangeness-changing weak charged current. We calculate the total cross sections for all possible channels and estimate the flux-averaged total cross sections for experiments like MiniBooNE, SciBooNE, T2K, and Minerva. The model is based on the lowest order effective SU(3) chiral Lagrangians in the presence of an external weak charged current and contains Born and the lowest-lying decuplet resonant mechanisms that can contribute to these reaction channels. We also compare and discuss our results with others following similar and very different approaches.

Note that the flux taken for MiniBooNE, Ref. [ref] , corresponds to the antineutrino enhanced sample, while the flux taken from figure 1 of Ref. [ref] corresponds also to the $ν̅_μ$ flux, but in this case this is not the larger component of the flux, because the latter is the muon neutrino component.

It is interesting to see that the the total cross sections have the same order of magnitude as those of the single $K$ and $K̅$ production ($1K/K̅$) cross sections off nucleons studied in Refs. [ref] .
