Description

Abstract Semi-inclusive hadron-production processes are becoming important in high-energy hadron reactions. They are used for investigating properties of quark-hadron matters in heavy-ion collisions, for finding the origin of nucleon spin in polarized lepton-nucleon and nucleon-nucleon reactions, and possibly for finding exotic hadrons. In describing the hadron-production cross sections in high-energy reactions, fragmentation functions are essential quantities. A fragmentation function indicates the p... Title of program: ffevol1.0 Catalogue Id: AELJ_v1_0 Nature of problem This program solves timelike DGLAP Q 2 evolution equations with or without next-to-leading-order α s effects for fragmentation functions. The evolved functions can be calculated for D h g , D h u , D h ubar , D h d , D h dbar , D h s , D h sbar , D h c , D h cbar , D h b and D h bbar of a random hedron h. Versions of this program held in the CPC repository in Mendeley Data AELJ_v1_0; ffevol1.0; 10.1016/j.cpc.2011.12.022 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
