PROTON STRUCTURE
QCD Fit HERAPDF1.5LO:
H1prelim-13-141, ZEUS-prel-13-003Part of the HERA II data has been combined (H1-prelim-10-141,ZEUS-prel-10-017). The PDF set HERAPDF1.5 represents the QCD analysis of the combined HERA I including the preliminary combination of the HERA II data. Such, higher precision at high Q2 and high x is achieved. The precision of the PDFs at high x is significantly improved, particularly in the valence sector.
