“…The NC data cover a wide range in x and Q 2 . The lowest Q 2 ≥ 0.045 GeV 2 data come from the measurements of ZEUS using the BPC and BPT [6,7]. The Q 2 range from 0.2 GeV 2 to 1.5 GeV 2 is covered using special HERA runs, in which the interaction vertex position was shifted forward allowing for larger angles of the backward scattered electron to be accepted [1,8,35].…”

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.

“…In order to cover the detector acceptance gap between the DIS regime of a few GeV 2 in Q 2 and photoproduction (Q 2 = 0 GeV 2 ), ZEUS installed in 1995 a small electromagnetic calorimeter (the 'beam pipe calorimeter') with good energy and position resolution around the beampipe. This device extended the ZEUS acceptance down to Q 2 = 0.1 GeV 2 , allowing the desired measurements of the virtual photon-proton scattering cross section or F 2 in the transition region [6]. Figure 7 shows the resulting F 2 as a function of x for Q 2 = 0.11 − 6.0 GeV 2 .…”
