Study of Neutrino Oscillations

Leaders:

D.V. Naumov
A.G. Olshevsky


Participating countries and international organizations:

China, Czech Republic, France, Germany, Japan, Italy, Romania, Russia, Slovakia, Switzerland, Turkey, USA.


Issues addressed and main goals of research:

  • Measurement of the neutrino mixing angle  θ  and the squared mass difference  Δ m 2ee in Daya Bay experiment.

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

  • Measurement of the solar neutrino fluxes, search for the sterile neutrino state and new particles.

  • Study of tau-neutrino production in proton-nuclear interactions at CERN SPS.

  • Development of the Light Collection System for LiAr of the DUNE ND.


Expected results in the current year:

  • Physics analysis of the Daya Bay experiment data on determination of θ13 and other oscillation parameters.

  • An estimation of the mass hierarchy measurements precision in the JUNO experiment with the TAO near detector.

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

  • Data analysis in the NOvA experiment, new results on hierarchy and CP.

  • Mass test of JUNO PMT with scanning stations.

  • Monitoring of the JUNO veto system planes with cosmic muons.

  • Installation and commissioning of the JUNO detector (PMT, HV, TT-veto).

  • Development of the GNA project: GPU support and automatic differentiation.

  • Preparation of the full physics run and data analysis of pilot run data, development of algorithms of charm particles decay search in high track density conditions.

  • Analysis of solar neutrino parameters and search for rare processes in the Borexino detector, DS-50 data analysis.
