Revamping Kaluza-Klein dark matter in an orbifold theory of flavor

TL;DR

This paper presents a unified model linking dark matter, neutrino masses, and flavor symmetry using orbifold compactification, with WIMP dark matter arising from Kaluza-Klein excitations and consistent flavor predictions.

Contribution

It introduces a novel orbifold theory that naturally connects dark matter, neutrino mass generation, and family symmetry within a single framework.

Findings

WIMP dark matter from Kaluza-Klein scalar excitation

Successful explanation of quark-lepton mass relations

Predictions for neutrinoless double beta decay

Abstract

We suggest a common origin for dark matter, neutrino mass and family symmetry within the orbifold theory proposed in [arXiv:1910.05605v2,arXiv:2004.06735v2]. Flavor physics is described by an $A_4$ family symmetry that results naturally from compactification. WIMP Dark matter emerges from the first Kaluza-Klein excitation of the same scalar that drives family symmetry breaking and neutrino masses through the inverse seesaw mechanism. In addition to the "golden" quark-lepton mass relation and neutrino predictions for $0\nu\beta\beta$ decay, the model provides a good global description of all flavor observables.
