Participating countries and international organizations:
China, Czech Republic, France, Germany, Japan, Italy, Romania, Slovakia, Turkey, USA.

Issues addressed and main goals of research:

  • Measurement of the neutrino mixing angle  and the squared mass difference  m 2ee in Daya Bay experiment.

  • Measurement of the solar neutrino fluxes in the Borexino experiment, search for the sterile neutrino state.

  • Study of the neutrino oscillations in the OPERA experiment.

  • Neutrino mass hierarchy determination and measurement of the CP violation phase of the neutrino mixing matrix in the JUNO and NOvA experiments.

  • R&D for the new photo detectors and detector equipment for the neutrino experiments.

  • Improvement of the precision of the direct solar neutrino flux measurements with the Borexino detector, phase-II experiment.

Expected results in the current year:

  • Physics analysis of the Daya Bay experiment data on  determination.

  • Precision estimation of the mass hierarchy measurements and determination of neutrino oscillation parameters in the NOvA and JUNO experiments by different methods.

  • Data analysis in the NOvA experiment.

  • Study of systematic uncertainties related to the neutrino-nucleon cross sections for the NOvA analysis.

  • Use of NOvA experiment Remote Operation Centre at JINR for shifts.

  • Start of the mass production of the high voltage system for JUNO PMTs.

  • Mass test of JUNO PMT with scanning stations.

  • Monitoring of the JUNO veto system planes.

  • Reconstruction of events in the Borexino detector.

  • Analysis of SNO solar neutrino parameters in the Borexino detector.
