# 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.

## Key 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.
