Laurent Simard, (for the NEMO-3, the SuperNEMO collaboration)
TL;DR
The paper discusses the NEMO-3 experiment's investigation of neutrinoless double beta decay and the development of the SuperNEMO detector aiming for higher sensitivity and reduced background.
Contribution
It introduces the SuperNEMO project with new detector components and R&D efforts to improve sensitivity and background reduction in neutrinoless double beta decay detection.
Findings
NEMO-3 is collecting data underground.
SuperNEMO aims for a half-life sensitivity of 10^26 years.
R&D on detector components is underway.
Abstract
The NEMO experiment is investigating the neutrinoless double beta decay. The NEMO-3 detector is taking data in the Frejus Underground Laboratory. The goal of the SuperNEMO detector is to reach a sensitivity on the order of 10^26 year on the half-life of the bb0nu process. The chosen isotopes for the future detector are 82Se and 150Nd, because of the reduced background. The collaboration has started a 3-year R&D development on all components : tracking detector, calorimeter, source enrichment and purification, radiopurity measurements.
