Neutrinoless double beta decay constrained by the existence of large extra dimensions

TL;DR

This paper investigates how large extra spatial dimensions could influence the half-life of neutrinoless double beta decay, focusing on the Majorana neutrino mass mechanism within the Arkani-Hamed--Dimopoulos--Dvali model.

Contribution

It introduces a novel analysis of neutrinoless double beta decay constraints considering large extra dimensions in a specific theoretical framework.

Findings

Large extra dimensions can significantly alter decay half-life predictions

Constraints on neutrino mass are affected by the number of extra dimensions

The model provides new bounds on extra dimension parameters

Abstract

We present the possible influence on the half-life of neutrinoless double beta decay coming from the existence of $n$ extra spatial dimensions. The half-life in question depends on the mass of the electron neutrino. We base our analysis on the Majorana neutrino mass mechanism in Arkani-Hamed--Dimopoulos--Dvali model.
