Description
Precision electroweak observables such as the Peskin--Takeuchi S parameter have long been used to constrain models of electroweak symmetry breaking that involve new strong dynamics. However, nonperturbative calculations of S from first principles have previously only been performed for QCD. I present initial results by the Lattice Strong Dynamics (LSD) Collaboration for the S parameter in SU(3) gauge theory with 2 and 6 flavors of fermions in the fundamental representation.
