Description

Abstract We investigate a numerical solution of the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) Q^2evolution equation for the transversity distribution Δ_T q or the structure function h_1 . The leading-order (LO) and next-to-leading-order (NLO) evolution equations are studied. The renormalization scheme is MS or MS in the NLO case. Dividing the variables x and Q^2into small steps, we solve the integrodifferential equation by the Euler method in the variable Q^2and by the Simpson method in... Title of program: H1EVOL Catalogue Id: ADHY_v1_0 Nature of problem This program solves the DGLAP Q^2 evolution equation with or without next-to-leading-order (NLO) alphas effects for a transversely polarized parton distribution, so called transversity distribution Delta_Tq or chiral-odd structure fuction h1. Versions of this program held in the CPC repository in Mendeley Data ADHY_v1_0; H1EVOL; 10.1016/S0010-4655(98)00028-9 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
