Strange particle production at RHIC in the Dual Parton Model

Abstract

We compute the mid-rapidity densities of pions, kaons, baryons and antibaryons in $Au$-$Au$ collisions at $\sqrt{s}=$ 130 GeV in the Dual Parton Model supplemented with final state interaction (comovers interaction). The ratios $B/n_{part}$ ($\bar{B}/n_{part}$) increase between peripheral ($n_{part}=18$) and central ($n_{part}=350)$ collisions by a factor 2.4 (2.0) for $\Lambda$'s, 4.8 (4.1) for $\Xi$'s and 16.5 (13.5) for $\Omega$'s. The ratio $K^{-}/{\pi }^{-}$ increases by a factor 1.3 in the same centrality range. A comparison with available data is presented.
