A (Slightly Less Brutal) Method for Numerically Evaluating Structure Functions
D. Fasching
Abstract
A fast numerical algorithm for the evolution of parton distributions in x space is described. The method is close in spirit to `brute' force techniques. The necessary integrals are performed by summing the approximate contributions from small steps of the integration region. Because it is a numerical evaluation it shares the advantage with brute force numerical integration that there are no restrictions placed on the functional form of the distributions to be evolved. However, an improvement in the approximation technique results in a significant reduction in the number of integration steps and a savings in time on the order of three hundred fifty. The method has been implemented for the structure functions F2 and g1 at next-to-leading order.
