M. Derrick et al., MEASUREMENT OF THE PROTON STRUCTURE-FUNCTION F2 AT LOW-X AND LOW Q(2)AT HERA, Zeitschrift fur Physik. C, Particles and fields, 69(4), 1996, pp. 607-620
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 1
5 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 p
revious 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 con
sistent with perturbative QCD.
