Abstract:
We report on a measurement of the proton structure functionF2 in the range 3.5×10−5≤x≤4×10−3 and 1.5 GeV2≤Q2≤15GeV2 at theep collider HERA operating at a centre-of-mass energy of √s=300GeV. The rise ofF2 with decreasingx observed in the previous HERA measurements persists in this lowerx andQ2 range. TheQ2 evolution ofF2, even at the lowestQ2 andx measured, is consistent with perturbative QCD.
