Electroweak Precision Tests of the Standard Model after the Discovery of the Higgs Boson
2019
The global fit of the
Standard Modelpredictions to electroweak precision data, which has been routinely performed in the past decades by several groups, led to the prediction of the
top quarkand the
Higgs bosonmasses before their respective discoveries. With the measurement of the
Higgs bosonmass at the
Large Hadron Collider(LHC) in 2012 by the ATLAS and CMS collaborations, the last
free parameterof the
Standard Modelof
particle physicshas been fixed, and the global electroweak fit can be used to test the full internal consistency of the electroweak sector of the
Standard Modeland constrain models beyond. In this article, we review the current state-of-the-art theoretical calculations, as well as the precision measurements performed at the LHC, and interpret them within the context of the global electroweak fit. Special focus is drawn in the impact of the
Higgs bosonmass on the fit.
