We report on a measurement of the proton structure function F-2 in the range 3.5 x 10(-5) less than or equal to x less than or equal to 4 x 10(-3) and 1.5 GeV2 less than or equal to Q(2) less than or equal to 15 GeV2 at the ep collider HERA operating at a centre-of-mass energy of root s = 300 GeV. The rise of F-2 with decreasing x observed in the previous HERA measurements persists in this lower x and Q(2) range. The Q(2) evolution of F-2, even at the lowest Q(2) and x measured, is consistent with perturbative QCD.

Abstract

We report on a measurement of the proton structure function F-2 in the range 3.5 x 10(-5) less than or equal to x less than or equal to 4 x 10(-3) and 1.5 GeV2 less than or equal to Q(2) less than or equal to 15 GeV2 at the ep collider HERA operating at a centre-of-mass energy of root s = 300 GeV. The rise of F-2 with decreasing x observed in the previous HERA measurements persists in this lower x and Q(2) range. The Q(2) evolution of F-2, even at the lowest Q(2) and x measured, is consistent with perturbative QCD.
