# TASI Lectures on Future Colliders

## TL;DR

This paper reviews the motivations, challenges, and potential physics reach of future high-energy colliders, especially electron-positron and proton-proton circular colliders, for understanding electroweak symmetry breaking and beyond Standard Model physics.

## Contribution

It provides a comprehensive overview of the scientific goals and technical challenges of upcoming collider projects, highlighting their expected contributions to fundamental physics.

## Key findings

- Future colliders can significantly advance understanding of electroweak symmetry breaking.
- Circular colliders have promising potential for exploring physics beyond the Standard Model.

## Abstract

These lectures review the main motivations for future high-energy colliders, focusing on the understanding of electroweak symmetry breaking and on the search for physics beyond the Standard Model. The open questions and the challenges are common to all future projects; for concreteness, I will use studies of the potential of $\rm e^+e^-$ and pp circular colliders to provide examples of the anticipated physics reach.
