| Abstract |
The cross-section normalised scaled momentum distribution (xp) of charged final state hadrons has been measured in DIS ep collisions by H1 at High Q2 in the Breit frame of reference. Compared with previous results presented by HERA experiments this analysis has significantly higher statistics, extends to higher Q2, and to the full range of xp. The results are compared with different models of the Fragmentation process as implemented in leading order Monte Carlo models with either parton showers or the colour dipole model of higher order QCD radiation. The results are also compared with an NLO calculation (CYCLOPS). |
