Two-loop SUSY QCD correction to the gluino pole mass

Abstract

The pole mass of the gluino is diagrammatically calculated to the two-loop order in SUSY QCD as a function of the running parameters in the lagrangian, for the gluino and squarks sufficiently heavier than the quarks. The O(alpha_s^2) correction shifts the gluino mass by typically 1-2 %, which may be larger than the expected accuracy of the mass determination at future colliders.
