Issues addressed and main goals of research:

• Measurement of the neutrino mixing angle θ₁₃ and the squared mass difference Δm²_ee in the 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 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 LiAr Light Collection System 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.
  
  
• Estimation of the mass hierarchy measurements precision in the JUNO experiment with the TAO near detector.
  
  
• Use of the NOvA experiment Remote Operation Centre at JINR for shift working.
  
  
• Data analysis in the NOvA experiment, new results considering the hierarchy and CP.
  
  
• Mass test of JUNO PMTs 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 the 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, the DS-50 data analysis.
