We have improved the tree-level model of Ref. [1] for weak production of kaons off nucleons by partially restoring unitarity. This is achieved by imposing Watson's theorem to the dominant vector and axial-vector contributions in appropriate angular momentum and isospin quantum number sectors. The observable consequences of this procedure are investigated.

核子和Watson定理的弱kaon产生

我们改进了Ref的树级模型。[1]通过部分恢复单一性，弱化了核子上的钾离子的产生。这是通过在适当的角动量和同位旋量子数扇区中对主要矢量和轴向矢量贡献施加Watson定理来实现的。研究了此过程的可观察到的结果。
