Priority:

Status:

In-progress

Study of Neutrino Oscillations

Leader:	Yu.A. Gornushkin
Deputy:	O.Yu. Smirnov

Participating Countries, Institutes and International organizations:
Belgium, CERN, China, Croatia, Czech Republic, France, Germany, Hungary, Japan, Italy, Russia, Spain, Switzerland, Ukraine, USA.

Scientific Programme:

Search for long-baseline neutrino oscillation and study of neutrino oscillation parameters with the OPERA detector in the CNGS beam (CERN--Gran Sasso) OPERA project.
Direct solar neutrino flux measurements with the BOREXINO detector -- phase-II experiment.
Improving of the precision of the ₁₃ neutrino mixing angle measurement in the Daya Bay experiment.

Expected main results in 2014:

Scanning and analysis of the OPERA nuclear emulsion at JINR.
Software development for the Target Tracker data analysis. Development of the Brick Finding software, analysis of the electronic detector data and event vertex location.
Continuation of the data taking with the BOREXINO detector.
Improvement of the position reconstruction algorithm for the BOREXINO detector.
The study seasonal variations of the solar neutrino flux.
Precise measurement of the pp-neutrino flux with total errors down to 15%.
Improvement of the current results on the effective solar neutrino magnetic moment.
Improvement of the current result on the e reactions.
Development of Monte Carlo software for background simulation in the Daya Bay experiment.
Participation in data analysis for ₁₃ mixing angle measurement in the Daya Bay experiment.
