A simple inert model solves the little hierarchy problem and provides a dark matter candidate

TL;DR

This paper proposes a minimal extension to the Standard Model adding two singlet scalars to address the little hierarchy problem and provide a dark matter candidate, with testable direct detection signals.

Contribution

It introduces a simple inert scalar model that cancels quadratic Higgs corrections and offers a dark matter candidate with experimentally accessible detection prospects.

Findings

Model cancels one-loop quadratic corrections to Higgs mass.

Predicts a viable dark matter candidate.

Suggests detectable signals in future nuclear scattering experiments.

Abstract

We discuss a minimal extension to the standard model in which two singlet scalar states that only interacts with the Higgs boson is added. Their masses and interaction strengths are fixed by the two requirements of canceling the one-loop quadratic corrections to the Higgs boson mass and providing a viable dark matter candidate. Direct detection of the lightest of these new states in nuclear scattering experiments is possible with a cross section within reach of future experiments.
