SuperNEMO - the next generation double beta decay experiment

TL;DR

SuperNEMO is a next-generation experiment designed to detect neutrinoless double beta decay, aiming to determine if neutrinos are Majorana particles by employing advanced tracking and calorimetry techniques with 82 Se.

Contribution

It introduces the design and expected capabilities of SuperNEMO, an improved experiment building on NEMO-3 to enhance sensitivity to rare decay events.

Findings

Projected sensitivity to half-life of 2 x 10^26 years

Potential to measure Majorana neutrino masses around 50 meV

Successful adaptation of tracking and calorimetry techniques

Abstract

The SuperNEMO experiment is being designed to search for neutrinoless double beta decay to test if neutrinos are Majorana particles. The experimental technique follows that of the currently running NEMO-3 experiment, which successfully combines tracking and calorimetry to measure the topology and energy of the final state electrons. Unique particle identification capabilities of SuperNEMO will be employed with about 100 kg of 82 Se and will reach sensitivity to a half-life of about 2 x 10^26 years, which corresponds to Majorana neutrino masses of about 50 meV, depending on the calculated value of the nuclear matrix element. In this poster, the current status of the SuperNEMO project is presented.
