Resonance Model ofΛ−K0Production

Abstract

A resonance model is proposed to explain the excitation function, the angular distribution, and the large polarization of $\Lambda$ in the reaction $p+{\pi }^{-}\to \Lambda +K^0$. It is assumed that there exists a low angular momentum resonance in the channel $p+{\pi }^{-}\to \left(\mathrm{resonant}\mathrm{state}\right)\to \Lambda +K^0$.
