Production of meson resonances as leading particles in jets in proton-proton collisions at $$\sqrt s = 62$$ GeV at the CERN ISR

Abstract

The production of ρ(770)0,K *(892)0, $$\bar K^* (892)^0 $$ andf 2(1270) mesons as leading particles in hadron jets (<z>∼0.7) has been measured in deep inelasticpp interactions at the CERN ISR at $$\sqrt s = 62$$ GeV. The comparison of vector and pseudoscalar meson production at the same transverse momentum provides a rather model independent way to determine the fragmentation parameterV/P. We determine(V/P) u,d =1.66±0.18±0.63 from the ρ/π ratio and(V/P) s =0.90±0.13±0.27 from theK */K ratio. For thef 2(1270) production we findf 2/ρ0=0.30±0.08.
