Abstract
We present results on a high statistics study of the proton structure functions F2(x, Q2) and R=σL/σT measured in deep inelastic scattering of muons on a hydrogen target. The analysis is based on 1.8 × 106 events after all cuts, recorded at beam energies of 100, 120, 200 and 280 GeV and covering a kinematic range 0.06 ⩽ x ⩽ 0.80 and 7 GeV2 ⩽Q2 ⩽260 GeV2. At small x, we find R to be different from zero in agreement with predictions of perturbative QCD.
