A minimal model linking two great mysteries: neutrino mass and dark matter

TL;DR

This paper proposes a minimal, testable model linking neutrino masses with dark matter properties, predicting observable signals in low-energy experiments and at the LHC, and enabling cross-verification through multiple data sources.

Contribution

It introduces a simple model connecting neutrino mass generation with dark matter, with testable predictions for experiments and collider searches.

Findings

Light particles, including dark matter, detectable in low-energy experiments.

Heavy particles may produce observable signals at the LHC.

Model allows cross-checking through LHC data and neutrino/ LFV measurements.

Abstract

We present an economic model that establishes a link between neutrino masses and properties of the dark matter candidate. The particle content of the model can be divided into two groups: light particles with masses lighter than the electroweak scale and heavy particles. The light particles, which also include the dark matter candidate, are predicted to show up in the low energy experiments such as $(K\to \ell +{\rm missing energy})$, making the model testable. The heavy sector can show up at the LHC and may give rise to Br($\ell_i \to \ell_j \gamma$) close to the present bounds. In principle, the new couplings of the model can independently be derived from the data from the LHC and from the information on neutrino masses and Lepton Flavor Violating (LFV) rare decays, providing the possibility of an intensive cross-check of the model.
