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 13 neutrino mixing angle and  m 2ee squared mass difference in Daya Bay experiment. 

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

  • Study of the neutrino oscillations in OPERA experiment. 

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

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

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

Expected major results in the current year:

  • Physics analysis of the Daya Bay experiment data. 

  • Development of the methods of the mass hierarchy measurements and determination of neutrino oscillation parameters in NOvA and JUNO experiments. 

  • Data analysis in NOvA experiment. 

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

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

  • Preparation for the mass production of High Voltage for JUNO PMT. 

  • Mass test of JUNO PMT. 

  • Preparation of the OPERA TT detectors for the use in JUNO experiment. 

  • Measurement of JUNO veto system detector planes. 

  • Event reconstruction in Borexino detector. 

  • Analysis of SNO solar neutrino parameters in Borexino detector.
