Framework for an asymptotically safe Standard Model via dynamical breaking

TL;DR

This paper proposes a new theoretical framework embedding the Standard Model into an asymptotically-safe theory with a well-defined UV fixed point, where electroweak symmetry breaking occurs radiatively without free parameters.

Contribution

It introduces a consistent embedding of the Standard Model into an asymptotically-safe theory with a unique UV fixed point and radiative symmetry breaking, reducing free parameters.

Findings

Existence of a well-defined UV fixed point in the large colour/flavour limit.

Electroweak symmetry breaking driven radiatively by two mass-squared parameters.

No free parameters other than gauge couplings in the theory.

Abstract

We present a consistent embedding of the matter and gauge content of the Standard Model into an underlying asymptotically-safe theory, that has a well-determined in- teracting UV fixed point in the large colour/flavour limit. The scales of symmetry breaking are determined by two mass-squared parameters with the breaking of elec- troweak symmetry being driven radiatively. There are no other free parameters in the theory apart from gauge couplings.
