TL;DR

This paper introduces a novel class of natural models where new gauge bosons, related through an infrared fixed point, cancel one-loop divergences in the Higgs mass, potentially raising the scale of new physics to 5-10 TeV.

Contribution

It proposes a new symmetry-based cancellation mechanism involving gauge bosons and top-partners, extending ideas from Little Higgs models and integrating with supersymmetry.

Cancellation of one-loop divergences achieved

Potential to push new physics scale to 5-10 TeV

Mechanism links gaugino and stop masses for Higgs mass stability

Abstract

We explore a new class of natural models which ensure the one-loop divergences in the Higgs mass are cancelled. The top-partners that cancel the top loop are new gauge bosons, and the symmetry relation that ensures the cancellation arises at an infrared fixed point. Such a cancellation mechanism can, a la Little Higgs models, push the scale of new physics that completely solves the hierarchy problem up to 5-10 TeV. When embedded in a supersymmetric model, the stop and gaugino masses provide the cutoffs for the loops, and the mechanism ensures a cancellation between the stop and gaugino mass dependence of the Higgs mass parameter.
