# Directions for model building from asymptotic safety

## TL;DR

This paper investigates how to extend the Standard Model to be asymptotically safe at high energies by adding fermions and scalars, analyzing theoretical consistency and potential collider signatures.

## Contribution

It proposes minimal asymptotically safe extensions of the Standard Model involving higher-representation fermions and explores their phenomenological implications.

## Key findings

- Asymptotic safety requires fermions in higher representations.
- Potential collider signatures include R-hadron searches and diboson signals.
- The evolution of gauge couplings is consistent with asymptotic safety.

## Abstract

Building on recent advances in the understanding of gauge-Yukawa theories we explore possibilities to UV-complete the Standard Model in an asymptotically safe manner. Minimal extensions are based on a large flavor sector of additional fermions coupled to a scalar singlet matrix field. We find that asymptotic safety requires fermions in higher representations of $SU(3)_C\times SU(2)_L$. Possible signatures at colliders are worked out and include $R$-hadron searches, diboson signatures and the evolution of the strong and weak coupling constants.
