Strangeness and diquark suppression factors in 360 GeV/c pp interactions

Abstract From the measurements of the inclusive production ratios between π - , K - and p at Feynman x = 0 in 360 GeV/ c pp interactions and using the predictions of the Lund fragmentation model, we determine the strangeness and diquark suppression factors and find γ s , l = 0.28 ± 0.03 and γ D , l = 0.063 ± 0.011 .
