摘要：

A preliminary measurement is reported of the longitudinal proton structure function F-L(x,Q(2)) obtained from the HI 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(2) < 800 GeV2 Employing the energy dependence of the cross section, the measurement is based on inclusive deep inelastic 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-L values are compared with higher order QCD calculations based on parton densities obtained using cross section data previously measured at HERA.
