摘要：

Recent HERA low Q(2) data show that the logarithmic slope of the proton structure function (partial derivative F-2/partial derivative lnQ(2)) is significantly different from perturbative QCD expectations for small values of Q(2) at exceedingly small values of x. We show that shadowing (screening) corrections provide a natural explanation for this experimental observation. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
