Objetivo Investigation of double beta processes with the tracking detector NEMO-3. Neutrinoless double beta decay is one of the best probes for physics beyond the standard model of electro weak interactions. Its existence is tied to fundamental aspects of particle physics such as lepton number non conservation, neutrino mass, right-handed currents in the electro weak interaction, a mass less Goldstone boson (Majoron), the structure of the Higgs' sector and supersymmetry. The proposed experiment is to investigate double beta decay processes with a new low-background tracking detector, NEMO-3, able to study different isotopes with masses up to 10 kg. The first experimental run during of ~2 years will be performed with 7 kg of 100 Mo, 1 kg of 82 Se, 0.7 kg of 130 Te, 0.7 kg of very pure natural Te, 0.5 kg of 116 Cd, 50 g of 150 Nd, 10 g of 96 Zr, and 0.6 kg of very pure copper.Objectives are following:1) to study real characteristics of the detector, its radioactive background;2) to obtain limits on neutrinoless double beta decay of the isotopes under study exceeding current ones approximately 10-100 times;3) to investigate two-neutrino double beta decay of the isotopes with accuracy higher than current ones (half-lives, energy and angular distributions);4) to determine a real radioactive contamination of the sources and to select optimal techniques for ultra-low background purification;5) to continue theoretical investigations of double beta decay problem with the aim to improve the quality of nuclear matrix element calculations.
