摘要：

We compute the proton structure function F-2(p) at small x and large Q(2) at next-to-leading order in alpha(s)(Q(2)), including summations of all leading and subleading logarithms of Q(2) and 1/x. We perform a detailed comparison to the 1993 HERA data, and show that they may be used to determine alpha(s)(M(Z)(2)) = 0.120 +/- 0.005(exp) +/- 0.009(th). The theoretical error is dominated by the renormalization and factorization scheme ambiguities.
