Description

Abstract I report on a numerical program for the evolution of parton distributions. The program uses the Mellin-transform method with an optimized contour. Due to this optimized contour the program needs only a few evaluations of the integrand and is therefore extremely fast. In addition, the program can also be used to reproduce the results of the x-space method. Title of program: partonevolution version 1.0 Catalogue Id: ADQL_v1_0 Nature of problem Parameterizations of parton distributions are usually given at a fixed input scale Q0. To be used in perturbative calculations, they have to be evolved numerically to the desired scale Q. Versions of this program held in the CPC repository in Mendeley Data ADQL_v1_0; partonevolution version 1.0; 10.1016/S0010-4655(02)00584-2 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
