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 and the squared mass difference m ²_ee 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.
