Bound-state dark matter and Dirac neutrino mass

TL;DR

This paper introduces a model where dark matter consists of stable neutral hadronic relics and neutrino masses are generated radiatively through colored dark matter constituents, linking dark matter stability and neutrino properties.

Contribution

It presents a unified theory connecting dark matter and neutrino mass origins with testable predictions for direct detection and collider experiments.

Findings

Dark matter as stable neutral hadronic relics

Neutrino masses arise radiatively from colored dark matter

Model predicts signals for direct detection and colliders

Abstract

We propose a simple theory for the idea that cosmological dark matter (DM) may be present today mainly in the form of stable neutral hadronic thermal relics. In our model neutrino masses arise radiatively from the exchange of colored DM constituents, giving a common origin for both dark matter and neutrino mass. The exact conservation of $B-L$ symmetry ensures dark matter stability and the Dirac nature of neutrinos. The theory can be falsified by dark matter nuclear recoil direct detection experiments, leading also to possible signals at a next generation hadron collider.
