Methods in the LO Evolution of Nondiagonal Parton Distributions: The DGLAP Case

Abstract

In this paper, we discuss the algorithms used in the LO evolution program for nondiagonal parton distributions in the DGLAP region and discuss the stability of the code. Furthermore, we demonstrate that we can reproduce the case of the LO diagonal evolution within 0.5% of the original code as developed by the CTEQ-collaboration.
