Full one-loop corrections to squark decays — Wolfgang Hollik and •Ananda Landwehr — Max-Planck-Institut für Physik, München, Deutschland

In this talk the QCD and electroweak (EW) corrections to two-body decays of squarks within the minimal supersymmetric standard model (MSSM) are presented. The decay products considered are quark-gluino, quark-neutralino, quark-chargino, squark--W/Z-boson, and squark--higgs-boson. In particular we examine the third-generation squark decays where the decay channels to squark--W/Z-boson and squark--higgs-boson can become sizeable due to potentially large left-right mixing.

Special care has been taken concerning the renormalization of the Higgs and bottom/sbottom sectors. We combine the results for the various decay chains and present numerical analyses for the branching ratios.
