Radiative corrections in SUSY phenomenology

Abstract

We discuss some aspects of the radiative corrections in the phenomenology of the minimal SUSY standard model, by reviewing two recent studies. (1) The full one-loop corrections to the Higgs boson decays into charginos are presented, with emphasis on the renormalization of the chargino sector, including of their mixing matrices. (2) The two-loop O(alpha_s tan beta) corrections to the b -> s gamma decay in models with large tan beta, mainly those to the charged Higgs boson contributions, are discussed. Exact two-loop result is compared to an approximation used in previous studies.
