Neutrinoless Double Beta Decay: Present and Future

TL;DR

This paper reviews the current status and future prospects of neutrinoless double beta decay searches, emphasizing the experimental challenges and upcoming projects aiming to detect this rare process at very low neutrino mass scales.

Contribution

It provides a comprehensive overview of the present experimental landscape and outlines future plans to reach the sensitivity needed for observing neutrinoless double beta decay.

Findings

Recent neutrino oscillation observations suggest possible detection at 10-50 meV mass scale.

Achieving the necessary experimental sensitivity is a significant challenge.

Several new projects are proposed to reach the detection goals.

Abstract

Present status, and future plans for Double Beta Decay searches are reviewed. Given the recent observations of neutrino oscillations, a possibility to observe $\beta\beta(0\nu)$~ at a neutrino mass scale suggested by present experimental results ($m_{\nu} \approx$10-50 meV) could actually exist. The achievement of the required experimental sensitivity is a real challenge faced by a series of new proposed projects. Plans to achieve such a result are described.
