Influence of anisotropic $\Lambda /\Sigma$ creation on the ${\Xi }^{-}$ mutiplicity in subthreshold proton-nucleus collisions

Miklós Zétényi, György Wolf

We present an analysis of ${\Xi }^{-}$ baryon production in subthreshold proton--nucleus ($p+A$) collisions in the framework of a BUU type transport model. We propose a new mechanism for…
