Description

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract We present the C++ program library mr that allows us to reliably calculate the values of the running parameters in the Standard Model at high energy scales. The initial conditions are obtained by relating the running parameters in the MS renormalization scheme to observables at lower energies with full two-loop precision. The evolution is then performed in accordance with the renormalization group equations with full three-loop precision. Pure QCD corrections to the matching and run... Title of program: mr Catalogue Id: AFAI_v1_0 Nature of problem The running parameters of the Standard Model renormalized in the MS scheme at some high renormalization scale, which is chosen by the user, are evaluated in perturbation theory as precisely as possible in two steps. First, the initial conditions at the electroweak energy scale are evaluated from the Fermi constant G F and the pole masses of the W , Z, and Higgs bosons and the bottom and top quarks including the full two-loop threshold corrections. Second, the evolution to the high energy scale i ... Versions of this program held in the CPC repository in Mendeley Data AFAI_v1_0; mr; 10.1016/j.cpc.2016.04.017
