Study of Neutrino Oscillations


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

Participating Countries and International Organizations:
China, Czech Republic, France, Germany, Japan, Italy, Slovakia, Turkey, USA.
Scientific Programme:

  • Measurement of the 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 main results in 2018:
    • Physics analysis of the Daya Bay experiment data.

    • Sensitivity optimization to the mass hierarchy measurements and determination of neutrino oscillation parameters.

    • Application of software algorithms for event reconstruction in NOvA experiments.

    • Study of NOvA experiment systematic uncertainties related to the neutrino-nucleon cross sections and MSW effects for current NOvA analysis.

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

    • Test of High Voltage prototype for JUNO PMT.

    • Measurement of JUNO PMT characteristics.

    • OPERA emulsions analysis at JINR.

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

    • Measurement of JUNO veto system prototype at JINR using OPERA detectors.

    • Event coordinates reconstruction in Borexino detector.

    • Analysis of solar neutrino parameters in Borexino detector.
