D. Lalanne (LAL)
TL;DR
This paper reports initial results from the NEMO-3 detector's search for neutrinoless double beta decay, providing new half-life measurements and limits on neutrino mass for multiple isotopes.
Contribution
It presents the first experimental results from NEMO-3, including detector performance, particle identification, and new limits on neutrinoless double beta decay.
Findings
New half-life values for Mo100, Se82, Nd150, Zr96, Ca48
Stronger limits on the effective neutrino mass from Mo100 and Se82 data
Detailed detector performance and particle identification methods
Abstract
The NEMO 3 detector has been running since February 2003 with several double beta emitters. New results are given for Mo100, Se82, Nd150, Zr96, Ca48. The NEMO 3 detector properties are presented for tracking reconstruction, identification of particles, energy measurement. Angular distributions for one and two electrons are produced as well as energy spectra. It is deduced new values of half lives for the double beta emitters and stronger limits on the effective neutrino mass using data on Mo100 and Se82.
