Status: Extended

Study of Neutrino Oscillations


Leaders:     D.V. Naumov
A.G. Olshevskiy

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.
