Constraining holographic technicolor

Year: 2012

Type: article

Abstract: We obtain a new bound on the value of Peskin–Takeuchi S parameter in a wide class of bottom-up holographic models for technicolor. Namely, we show that weakly coupled holographic description in these models implies S≫0.2. Our bound is in conflict with the results of electroweak precision measurements, so it strongly disfavors the models we consider.
