Issues addressed and main goals of research:

1. Measurement of the neutrino mixing angle θ₁₃ and the squared mass difference Δm²_ee in the Daya Bay experiment.
   
   
2. Neutrino mass hierarchy determination and measurement of the CP violation phase of the neutrino mixing matrix in the JUNO and NOvA experiments.
   
   
3. Measurement of solar neutrino fluxes, search for the sterile neutrino state and new particles.
   
   
4. Study of tau neutrino production in proton-nuclear interactions at the CERN SPS.
   
   
5. Development of detector systems of the DUNE ND.

Expected results in the current year:

1. Physics analysis of the Daya Bay experiment data on determination of θ₁₃ and other oscillation parameters.
   
   
2. Estimation of the mass hierarchy measurement precision in the JUNO experiment with the TAO Near Detector.
   
   
3. Tests of detection elements and electronics of JUNO/TAO.
   
   
4. Installation and commissioning of the JUNO detector (PMT, HV, TT-veto).
   
   
5. Using of the NOva Remote Operation Centre at JINR for shift working, mass testing of JUNO PMTs with scanning stations.
   
   
6. Data analysis in the NOvA experiment, new results considering the hierarchy and CP monitoring of the JUNO veto system planes with cosmic muons.
   
   
7. Preparation of prototype tests of DUNE ND detector systems.
   
   
8. Development of the GNA project: GPU support and automatic differentiation.
   
   
9. Preparation of the full physics run and data analysis of the pilot run data, development of algorithms of charm particles decay search in high track density conditions.
   
   
10. Analysis of solar neutrino parameters and search for rare processes in the Borexino detector, the DS-50 data analysis.
