Täuber, Uwe C.Schwabl, Franz2016-10-012016-10-011992-08-010163-1829http://hdl.handle.net/10919/73147We use the LEP/SLD data to place constraints on Topcolor Assisted Technicolor Models. We find that due to a large negative shift in R<sub>b</sub> induced by charged top-pion exchange, it is difficult to make the models compatible with experiment.3337 - 3361 page(s)application/pdfenIn CopyrightCritical dynamics of the O(n)-symmetric relaxational models below the transition temperatureArticle - RefereedThe American Physical SocietyPhysical Review Bhttps://doi.org/10.1103/PhysRevB.46.3337466
