Influence of anisotropic Λ/Σ creation on the Ξ− multiplicity in subthreshold proton–nucleus collisions
We present an analysis of Ξ− baryon production in subthreshold proton–nucleus (p+A) collisions in the framework of a BUU type transport model. We propose a new mechanism for Ξ production in the collision of a secondary Λ or Σ hyperon and a nucleon from the target nucleus. We find that the Ξ− multipl...
