We study constraints on Composite Higgs models with fermion partial compositeness from electroweak precision measurements, including the 2022 W-boson mass result from the CDF collaboration. We find good agreement between the full composite models and the current electroweak precision measurement bounds on S and T from LEP and CDF, including the offset and correlation of S, T with respect to the SM predictions.
We study constraints on Composite Higgs models with fermion partial compositeness from electroweak precision measurements, including the 2022 W-boson mass result from the CDF collaboration. We focus on models where the Composite Higgs sector arises from underlying four-dimensional strongly interacting gauge theories with fermions, and where the SM fermions obtain their mass via linear mixing terms between the fermions and the composite sector - the so-called fermion partial compositeness scenario. In general, the Composite Higgs sector leads to a small and positive S parameter, and a negative T parameter, but the fermion partial compositeness sector results in an overall positive T parameter in a large part of parameter space. We, therefore, find good agreement between the full composite models and the current electroweak precision measurement bounds on S and T from LEP and CDF, including the offset and correlation of S, T with respect to the SM predictions.
