Description

Abstract MENLO_PARC is a general purpose Monte Carlo program for calculating the next-to-leading order script O sign(α^3 _s ) corrections to four-jet quantities in electron-positron annihilation. Any quantity which can be constructed out of the four jet momenta and which is insensitive to the quark helicities and the beam orientation can be computed. Both virtual photon and Z intermediate states (and γ-Z interference) are included, hence the quantities can be computed for arbitrary center of mass ener... Title of program: MENLO_PARC Catalogue Id: ADGS_v1_0 Nature of problem The expansion in the strong coupling constant of any four-jet quantity in electron-positron annihilation starts only at O(alphas^2). As a result, the dependence of the theoretical predictions on the renormalization scale is very large. The only reliable way to reduce this dependence and, therefore, get more precise predictions is to include the full next-to-leading order correction. Versions of this program held in the CPC repository in Mendeley Data ADGS_v1_0; MENLO_PARC; 10.1016/S0010-4655(97)00093-3 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
