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.
