Hyperon Enhancement in the Dual Parton Model | | A. Capella
; C.A. Salgado

21 Jul 2000 | | Journal: | New J.Phys. 2 (2000) 30 | | Subject: | hep-ph | | Abstract: | We review the two sources of hyperon enhancement in the dual parton model: strings originating from diquark-antidiquark pairs in the nucleon sea and net baryons containing two or three sea quarks with a yield controlled by the observed stopping. We show that adding final state interactions (including strangeness exchange reactions as well as the inverse reactions required by detailed balance) with a single averaged cross-section $sigma=0.2$ mb, we can explain the observed hyperon enhancement in PbPb collisions at CERN SPS. | | Source: | arXiv, hep-ph/0007236 | | Services: | Forum | Review | PDF | Favorites | |
