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 Sâ«0.2. Our bound is in conflict with the results of electroweak precision measurements, so it strongly disfavors the models we consider.
