Asymptotic safety and Conformal Standard Model

TL;DR

This paper demonstrates that the Conformal Standard Model combined with asymptotically safe gravity remains valid at arbitrarily high energies and makes testable predictions for new particle masses.

Contribution

It introduces a framework integrating the Conformal Standard Model with asymptotically safe gravity, extending its validity to high energies.

Findings

Predicted second scalar particle mass around 300 GeV

Heavy neutrino masses around 340 GeV

Model testable in upcoming experiments

Abstract

We show that the Conformal Standard Model supplemented with asymptotically safe gravity can be valid up to arbitrarily high energies and give a complete description of particle physics phenomena. We restrict the mass of the second scalar particle to $\sim 300$ GeV and the masses of heavy neutrinos to $\sim 340$ GeV. These predictions can be explicitly tested in the nearby future.
