# Safe Clockwork

## TL;DR

This paper shows that safe quantum field theories can incorporate the clockwork mechanism, providing a fundamental framework that naturally generates Yukawa hierarchies and can be applied to models like the Pati-Salam theory.

## Contribution

It introduces a safe quantum field theory framework for the clockwork mechanism, enhancing its foundational understanding and application to the Standard Model.

## Key findings

- Safe quantum field theories can host the clockwork mechanism.
- The clockwork mechanism can naturally generate Yukawa hierarchies.
- A safe Pati-Salam clockwork structure is demonstrated.

## Abstract

In this letter we demonstrate that safe quantum field theories can accommodate the clockwork mechanism upgrading it to a fundamental theory a l\'a Wilson. Additionally the clockwork mechanism naturally sources Yukawa hierarchies for safe completions of the Standard Model (SM). As proof of concept we investigate a safe Pati-Salam (PS) clockwork structure.
