Proton Structure Measurements and the HERAPDF fit
arXiv:0906.1108
Abstract
New and previously published measurements on the deep inelastic scattering cross section by the H1 and ZEUS collaborations are presented. The uncertainties can be significantly reduced by a model independent combination procedure, which treats the systematic error correlations in a coherent way. The combined H1 and ZEUS measurements of the inclusive neutral and charged current cross sections are used to perform a common NLO QCD fit, called HERAPDF 0.1. The resulting set of parton density functions (PDFs) have a much improved experimental uncertainty compared to previous extractions using the uncombined H1 or ZEUS data.
