Scaled momentum distributions for KS0 and L in DIS at HERA

Research output: Contribution to journalConference articlepeer-review

Abstract

Results on the KS0 and L production in deep inelastic ep scattering at HERA obtained with ZEUS detector are presented. The scaled momentum distributions xp are measured in the current fragmentation region of the Breit frame as function of photon virtuality, Q2, in the kinematic region 10 < Q2 <40000 GeV2 and 0.001< x < 0.75 with x as the Bjorken variable. The data are compared to the leading-logarithm parton-shower Monte Carlo models which are using the same Lund fragmentation model and next-to-leading order QCD calculations. The measured distributions are compared to the those from the inclusive charged particles studies for the region of kinematic overlap, 0.1 < xp < 0.4, as functions of Q2.
