This study focuses on the Sigma pi and Lambda pi production off free nucleons driven by the strangeness-changing weak charged current. Total cross sections for all possible channels are calculated, and flux-averaged total cross sections are estimated for experiments like MiniBooNE, SciBooNE, T2K, and Minerva. The model, based on lowest order effective SU(3) chiral Lagrangians in the presence of an external weak charged current, includes Born and the lowest-lying decuplet resonant mechanisms, with comparisons and discussions with other approaches.
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 fluxaveraged 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.
