Abstract

The production of ρ(770)0,K*(892)0, $\bar K^* (892)^0$ andf2(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 thef2(1270) production we findf2/ρ0=0.30±0.08.
