Abstract

The lowest-order contributions to the decay mode Z→t¯c have been studied here in a supersymmetric E6 model containing "exotic" SU(2)-singlet charge −1/3 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.
