One-loop calculations for SUSY processes

Abstract

Strategy and results for complete one-loop computations in the Minimal Supersymmetric Standard Model are reviewed, with applications to the calculation of SUSY mass spectra and SUSY-particle processes. Determination of renormalization constants and counterterms are described in the on-shell renormalization scheme, and a translation between $\overline{\mathrm{DR}}$ and on-shell parameters is given. As an example, cross sections for chargino and neutralino pair production in $e^{+}{e}^{-}$ annihilation are presented, complete at the one-loop level.
