Abstract

We investigate the effects of top quark compositeness on various physical parameters, and obtain lower limits on the compositeness scale from electroweak precision data. We consider corrections to top quark decay rates and other physical processes. Our results depend sensitively on whether the left-handed top quark is composite. A considerable enhancement of tt¯ production is possible if only the right-handed top quark is composite.
