Decoupling relations and coefficient functions in SUSY-QCD to three loops — •Alexander Kurz, Matthias Steinhauser, and Nikolai Zerf — TTP Karlsruhe

A method to calculate decoupling relations between parameters of SUSY-QCD and of QCD is presented. It allows the computation of the decoupling constant of the strong coupling up to Os3) which constitutes an important ingredient in the relation between αs(MZ) and αs(MGUT). With the help of a low-energy theorem the calculated decoupling constant can be related to the effective coupling of the scalar Higgs boson to gluons. Similar considerations for the electromagnetic coupling leads to the decay rate of a Higgs boson to photons.
