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 2017:
  • 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.
