Abstract

Inclusive double differential cross sections for neutral current deep inelastic scattering are measured with the H1 detector at HERA. The data were taken with a lepton beam energy of GeV and two proton beam energies of and 575 GeV corresponding to centre-of-mass energies of 225 and 252 GeV, respectively. The measurements cover the region of for GeV up to . The measurements are used together with previously published H1 data at GeV and lower data at , and GeV to extract the longitudinal proton structure function in the region GeV.
