We report on a measurement of the proton structure function F_2 in the range 3.5 x 10^(−5) < x < 4 x 10^(−3) and 1.5 GeV^2 < Q^2 < 15 GeV^2 at the ep collider HERA operating at a centre-of-mass energy of sqrt(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) < x < 4 x 10^(−3) and 1.5 GeV^2 < Q^2 < 15 GeV^2 at the ep collider HERA operating at a centre-of-mass energy of sqrt(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.File in questo prodotto:
