Constraints on Topcolor Assisted Technicolor Models from Vertex Corrections

Abstract

We use the LEP/SLD data to place constraints on Topcolor Assisted Technicolor Models. We find that due to a large negative shift in R_b induced by charged top-pion exchange, it is difficult to make the models compatible with experiment.
