Extra Dimensions and Neutrinoless Double Beta Decay Experiments

TL;DR

This paper investigates how theories with large extra dimensions could influence neutrinoless double beta decay rates and assesses the potential for current experiments to test these theories.

Contribution

It links neutrinoless double beta decay half-life measurements to large extra dimension models using the Arkani-Hamed--Dimopoulos--Dvali framework.

Findings

Current experiments have the sensitivity to test certain extra dimensional scenarios.

The study provides a method to verify extra dimensions through neutrinoless double beta decay.

Results are discussed in the context of the Heidelberg--Moscow Collaboration data.

Abstract

The neutrinoless double beta decay is one of the few phenomena, belonging to the non-standard physics, which is extensively being sought for in experiments. In the present paper the link between the half-life of the neutrinoless double beta decay and theories with large extra dimensions is explored. The use of the sensitivities of currently planned $0\nu2\beta$ experiments: DAMA, CANDLES, COBRA, DCBA, CAMEO, GENIUS, GEM, MAJORANA, MOON, CUORE, EXO, and XMASS, gives the possibility for a non-direct `experimental' verification of various extra dimensional scenarios. We discuss also the results of the Heidelberg--Moscow Collaboration. The calculations are based on the Majorana neutrino mass generation mechanism in the Arkani-Hamed--Dimopoulos--Dvali model.
