Measurement of inclusive $$\varvec{ep}$$ e p cross sections at high $${\varvec{Q}^{2}}$$ Q 2 at $$\varvec{\sqrt{s}}=225$$ s = 225 and 252 GeV and of the longitudinal proton structure function $${\varvec{F}_{\varvec{L}}}$$ F L at HERA

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 E p = 460 and 575 GeV corresponding to centre-of-mass energies
