Abstract

We have calculated the low-energy constant L₁₀ in a prototype composite Higgs model with dynamical fermions in two different representations of the gauge group. The resulting contribution of the new strong sector to the S parameter is consistent with current bounds on the vacuum misalignment parameter. We end with a brief discussion of future directions.
