Measurement of the Proton Structure Function F{sub L}(x, Q{sup 2}) with the H1 Experiment
- University of Montenegro, Faculty of Science, Dzordza Vasingtona BB, 20000 Podgorica (Montenegro)
A preliminary measurement is reported of the longitudinal proton structure function F{sub L}(x, Q{sup 2}) obtained from the H1 experiment at the ep collider HERA. This is the first measurement of the longitudinal structure function in a range of squared four-momentum transfer 2.5<=Q{sup 2}<=800 GeV{sup 2}. Employing the energy dependence of the cross section, the measurement is based on inclusive deep inelastic e{sup +}p scattering cross section measurements with a positron beam energy of 27.5 GeV and proton beam energies of 920, 575 and 460 GeV. The measure F{sub L} values are compared with higher order QCD calculations based on parton densities obtained using cross section data previously measured at HERA.
