Calculating F_2^p at small x and large Q^2

Abstract

We show that the double asymptotic scaling of the HERA structure function data is consistent with pre-HERA data at larger $x$, soft pomeron behaviour at small $x$ and a sensible starting scale $Q_0$. We can thus actually calculate $F_2^p$ at small $x$ and large $Q^2$ by evolving up perturbatively at two loops, without any fitting.
