Abstract

In order to quantify isospin effects in the comparison of elementary to nuclear collisions, p-p and n-p interactions have been studied in the NA49 experiment in addition to p-Pb and Pb-Pb reactions. Together with first measurements of cascade hyperon and Omega production in p-p collisions, isospin-corrected K/pi ratios and cascade yields are discussed. The Antiomega/Omega ratio in p-p collisions is found to be less than 0.5 with 95% confidence level.
