Cross Sections and Structure Functions at Low and Medium Q2

H1 and ZEUS combined cross sections are presented in the low to medium Q2 range. The e±p scattering data used for the combination were collected during the period 1994–2000. The combined neutral and charged current data are used as input for a NLO QCD analysis which determines a new set of parton distribution functions HERAPDF1.0 with small experimental uncertainties. In addition, recent structure function measurements from H1 and ZEUS are also presented.
