## TL;DR

This paper explores how the Standard Model can exhibit quantum scale invariance at high Higgs field values without new particles, impacting the hierarchy problem, vacuum stability, and Higgs-driven inflation.

## Contribution

It introduces the concept of asymptotic scale invariance in the Standard Model and analyzes its implications for particle physics and cosmology.

## Key findings

- Potential metastability of the electroweak vacuum.
- Implications for Higgs inflation.
- Absence of new heavy particles needed for scale invariance.

## Abstract

Scale invariance supplemented by the requirement of the absence of new heavy particles may play an important role in addressing the hierarchy problem. We discuss how the Standard Model may become scale invariant at the quantum level above a certain value of the Higgs field value without addition of new degrees of freedom and analyze phenomenological and cosmological consequences of this setup, in particular, possible metastability of the electroweak vacuum and Higgs inflation.
