Fundamental Symmetries of the Early Universe and the Precision Frontier

TL;DR

This paper discusses how high-precision low-energy experiments complement high-energy colliders in exploring fundamental symmetries of the early universe and searching for new physics beyond the Standard Model.

Contribution

It highlights the importance of the precision frontier in providing unique insights into fundamental symmetries and its complementarity to collider experiments.

Findings

Precision experiments offer powerful probes of new physics.

Complementarity enhances the search for fundamental symmetries.

Future experiments will further clarify early universe physics.

Abstract

The search for the next Standard Model of fundamental interactions is being carried out at two frontiers: the high energy frontier involving the Tevatron and Large Hadron Collider, and the high precision frontier where the focus is largely on low energy experiments. I discuss the unique and powerful window on new physics provided by the precision frontier and its complementarity to the information we hope to gain from present and future colliders.
