Study of Neutrino Oscillations

Leaders:

D.V. Naumov
A.G. Olshevskiy

Participating Countries, Institutes and International organizations:
Czech Republic, Germany, Japan, Italy, Turkey, USA.

Scientific Programme:

Measurement of the ₁₃ neutrino mixing angle and m ²_ee 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 main results in 2015:

Development of our own selection of inverse beta decay (IBD) events and of various backgrounds to IBD events in the Daya Bay experiment. Study of background energy spectra. Reactor antineutrino flux and rate measurement in the Daya Bay experiment.
Study of quantum decoherence effects in neutrino oscillations taking into account Daya Bay data. Search for light sterile neutrino in the Daya Bay experiment.
Simulation, reconstruction and analysis software development for JUNO experiment.
Feasibility study of Top Muon Veto detector based on re-using of OPERA Target Tracker detector.
Development and tests of high voltage system for JUNO PMT.
Software development for the global analysis of neutrino oscillation data with the primary goal of combining reactor and accelerator neutrino data to measure the mass hierarchy.
Development of the event selection algorithms for the NOvA experiment.
Continuation of the data taking with the Borexino detector. Improvement of the position reconstruction algorithm.
Measurements with artificial neutrino source within sterile neutrino search project SOX (Borexino).
Measurement or setting limits of the solar neutrino flux from the CNO cycle (Borexino).
Improving of the current results on the effective solar neuntrino magnetic moment and on the e reaction (Borexino).
Search for the neutrino interactions by scanning and analysing nuclear emulsions from OPERA detector in JINR. Search for the new tau-neutrino candidates in OPERA experiment. Software development and data analysis for electron neutrino search in OPERA experiment.
OPERA detector decommission.
