Evidence for Large-xCorrections in Quantum Chromodynamics

We show there is evidence that a method of summing important logarithmic corrections which are significant in the large-$x$ region leads to a superior description of deep-inelastic scattering data (analyzed with use of the evolution equations). Next-to-leading-order calculations can imitate the impact of this summation method, but at high $x$ it appears that there are higher-order and higher-twist corrections which separate those approaches.
