Description

Inclusive ep 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 27.6 GeV and two proton beam energies of Ep = 460 and 575 GeV corresponding to centre-of-mass energies of 225 and 252 GeV, respectively. The measurements cover the region of 6.5x10^-4 ≤x ≤0.65 for 35≤Q^2≤800 GeV^2 up to y = 0.85. The measurements are used together with previously published H1 data at Ep = 920 GeV and lower Q^2 data at Ep = 460, 575 and 920 GeV to extract the longitudinal proton structure function FL in the region 1.5≤Q^2≤800 GeV^2.
