In this work we study the Σπ and Λπ 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.

Cabibbo 抑制了由反中微子引起的核子的单介子产生

在这项工作中,我们研究 ΣπΛπ由奇异变化的弱充电电流驱动的自由核子的产生。我们计算所有可能通道的总横截面,并估计 MiniBooNE、SciBooNE、T2K 和 Minerva 等实验的通量平均总横截面。该模型基于存在外部弱带电电流的最低阶有效 SU(3) 手性拉格朗日函数,并包含 Born 和可促成这些反应通道的最低层的十重共振机制。我们还采用类似和非常不同的方法与其他人比较和讨论我们的结果。
