F eb 1 99 6 A Study of the πB → Y K reactions for Kaon Production in Heavy Ion Collisions ∗

Abstract

Parametrizations of total cross sections sufficient for all channels of the πB → Y K reactions are completed using a resonance model. As well as discussing the πN → ΛK reactions, which were not presented in our previous publications, we present the differential cross section for πN → ΛK. This report also aims at presenting supplementary discussions to our previous work. One of the main goals of studying heavy ion collisions is to determine the equation of state (EOS) of nuclear matter. Because positive kaons (K) have a long mean free path inside the nucleus they are suggested as a good probe for the reactions occurring in the central region of the collisions [1]. Indeed, theoretical studies show that the kaons produced in heavy ion collisions are sensitive to the EOS [2, 3]. Although one can point out many important ingredients for the theoretical investigations of kaon production in heavy ion collisions, the discussions presented here are concerned with the elementary kaon production cross sections necessary for microscopic calculations. One of the purposes of this report is to complete the parametrizations of total cross sections sufficient for all channels of the πB → Y K reactions by a resonance model [7, 8] (B = N,∆ and Y = Λ,Σ). The results for the πN → ΛK reactions which were not given in our previous publications [7, 8] are given. Furthermore, supplementary disucussions to our previous work are presented.
