QCD corrections to the top quark decay mode {ital t}{r_arrow}{ital {tilde t}}{chi}{sup 0}
- Institut fuer Theoretische Physik, Universitaet Karlsruhe, D-76128 Karlsruhe (Germany)
In supersymmetric theories, the top quark can decay into its scalar partner plus a neutralino, with an appreciable rate. We calculate the {ital O}({alpha}{sub {ital s}}) QCD corrections to this decay mode in the minimal supersymmetric extension of the standard model. These corrections can be either positive or negative and increase logarithmically with the gluino mass. For gluino masses below 1 TeV, they are at most of the order of ten percent and, therefore, well under control. {copyright} {ital 1996 The American Physical Society.}
