Findings

Electroweak precision fits validate the Standard Model at high accuracy.

Deviations from predictions could signal new physics.

The approach provides a sensitive indirect probe for physics beyond the Standard Model.

Abstract

The Standard Model of particle physics provides a rigorous framework within which processes mediated by electroweak interactions can be calculated with great accuracy. By comparing with high-precision experimental measurements of the same processes, deviations from Standard Model predictions can be identified as indirect signals of new physics. In particular, electroweak precision fits combine multiple observables and provide a unique test of the Standard Model consistency at the quantum level.
