Abstract
The lowest-order contributions to the decay mode Z tc have been studied here in a supersymmetric E6 model containing "exotic" SU(2)-singlet charge -13 quarks. It is shown that the presence of such quarks give an appreciable boost to the branching ratio through not only weak one-loop diagrams but also gluino-induced ones. © 1989 The American Physical Society.
