Naturalness, Conformal Symmetry and Duality

TL;DR

This paper explores how duality and conformal symmetry might address the naturalness problem in effective field theories, suggesting that apparent unnaturalness could be an artifact of the effective theory approximation.

Contribution

It introduces a novel calculation scheme using hidden duality to potentially resolve naturalness issues in scalar masses within effective field theories.

Findings

Radiative corrections can be computed via duality-based methods.

Unnatural scalar mass corrections may be artifacts of effective theories.

Ultimate theories might naturally resolve naturalness problems.

Abstract

We reconsider the naturalness from the viewpoint of effective field theories, motivated by the alternative scenario that the standard model holds until a high-energy scale such as the Planck scale. We propose a calculation scheme of radiative corrections utilizing a hidden duality, in the expectation that the unnaturalness for scalar masses might be an artifact in the effective theory and it could be improved if features of an ultimate theory are taken in.
