SuperNEMO double beta decay experiment

TL;DR

SuperNEMO is an advanced double beta decay experiment building on NEMO3's design, aiming to detect neutrinoless double beta decay with high sensitivity to Majorana neutrino masses.

Contribution

It introduces a next-generation tracking plus calorimetry setup with a large isotope mass, enhancing sensitivity to rare decay processes.

Findings

Successfully completed R&D stage

Construction of the Demonstrator module underway

Projected sensitivity to $0 uetaeta$ half-life > $10^{26}$ years

Abstract

SuperNEMO is a next-generation double beta decay experiment based on the successful tracking plus calorimetry design approach of the recently stopped NEMO3 experiment. SuperNEMO can study a range of isotopes, but the baseline isotope is $^{82}$Se. The total isotope mass will be 100--200 kg. A sensitivity to a $0\nu\beta\beta$ half-life greater than $10^{26}$ years can be reached which gives access to Majorana neutrino masses of 50--100 meV. Having successfully completed R&D stage the SuperNEMO Collaboration has commenced the construction of the first module, the Demonstrator. The present status of SuperNEMO program and plan for the nearest future are discussed.
