Combined measurement and QCD analysis of the inclusive e ± p scattering cross sections at HERA


H1 Collaboration; Zeus Collaboration; et al; Egli, S; Nowak, K; Perez, E; Truöl, P (2010). Combined measurement and QCD analysis of the inclusive e ± p scattering cross sections at HERA. Journal of High Energy Physics, (1):109.

Abstract

A combination is presented of the inclusive deep inelastic cross sections measured by the H1 and ZEUS Collaborations in neutral and charged current unpolarised e ± p scattering at HERA during the period 1994-2000. The data span six orders of magnitude in negative four-momentum-transfer squared, Q 2, and in Bjorken x. The combination method used takes the correlations of systematic uncertainties into account, resulting in an improved accuracy. The combined data are the sole input in a NLO QCD analysis which determines a new set of parton distributions, HERAPDF1.0, with small experimental uncertainties. This set includes an estimate of the model and parametrisation uncertainties of the fit result.
