Participating Countries, Institutes and International Organizations:
Armenia, Belarus, Belgium, Bulgaria, Czech Republic, Finland, France, Germany, Kazakhstan, Mongolia, Poland, Romania, Russia, Slovak Republic, Ukraine, USA, Uzbekistan.

Scientific Programme:
Search for and investigation of double-neutrino and neutrinoless modes of double beta-decay, clarification of the Majorana neutrino nature, absolute neutrino mass scale and hierarchies. Search for the neutrino magnetic moment and dark matter. Investigation of galactic and extragalactic neutrino sources, diffusive neutrino cosmic background, search for exotic particles (monopoles). Application of the neutrino detector for a distant investigation of process inside of the reactor core of Kalininskaya Nuclear Power Plant. Search for sterile neutrinos. Spectroscopy of nuclei far from stability. Development of new methods for charged and neutral particle detection.

Expected main results in 2014:

Data taking in the 2-decay measurements of ¹⁵⁰Nd, ¹¹⁶Cd, ¹⁰⁶Cd, ¹⁰⁰Mo, ⁹⁶Zr, ⁸²Se, ⁴⁸Ca with the NEMO, TGV and GERDA spectrometers.
Processing of experimental data and determination of T_1/2(22) for ¹⁰⁰Mo, ⁸²Se and ⁷⁶Ge.
Data taking with the GEMMA-II spectrometer at the Kalinin Nuclear Power Plant; getting an upper limit for the neutrino magnetic moment at the level of ~ 2· 10 ^-11 µ _B.
In the EDELWEISS experiment a number of innovative improvements in the setup and detector's performances will be implemented. Forty of FID800 detectors will cumulative fiducial mass 24 kg will be installed in the upgraded EDELWEISS setup.The upgrade implies improved cryogenics, new cabling, installation of additional polyethelyne shield between the lead layer and the cryostat, supplementary muon veto modules, use of the new integrated DAQ and electronics, e.g. implemention of fast ionization channel with 40 MS/s. The goal of the project is to reach a WIMP-nucleon scattering cross-section sensitivity of 5· 10 ^-45 cm ². The detector research and development on longer term aims to reach a few 100 eV thresholds on both ionization and heat channels.
Research and development of the semiconductor-based detecting systems for the GERDA and MAJORANA experiments. Beginning of data taking in the experiment on the search for the ⁷⁶Ge 2 0-decay.
Mounting of the NT1000 prototype string. Data taking and extraction of physical results with the NT200+ spectrometer.
Investigation of the astrophysical S-factor and effective dd cross section in the 2-7 keV impact energy for the D₂O target.
Investigation of KLL and KMM Auger electrons in ⁶⁵Zn, ⁶⁷Cu, ⁶⁷Ga and ^152,154,155Eu decays.
Design and creation of the low-threshold (~ 200 eV) HPGe detector. Production of low-background plastic scintillators for the Super NEMO experiment.
Design and creation of the reactor antineutrino detector DANSS.
