Priority:

Status:

In-progress

Study of Neutrino Oscillations

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

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

Scientific Programme:

Long-baseline neutrino oscillation search and study of neutrino oscillation parameters with the OPERA detector in the CNGS beam (CERN-Gran Sasso)-project OPERA
Search for solar neutrino vacuum oscillations. Direct solar neutrino flux measurements, precise Ве ⁷ neutrino flux measurements with the BOREXINO detector.
Measurement of the ₁₃ neutrino mixing angle in the Daya Bay experiment.
Study of secondary hadron emission in p and interactions with nuclear targets for justification of the neutrino flux in the current experiments.

Expected main results in 2011:

Data taking with neutrinos from the CNGS beam at the OPERA detector.
Scanning and analysis of OPERA nuclear emulsion at JINR.
Software development for the Target Tracker data analysis. Development of the Brick Finding software, analysis of electronic detector data and event vertex location.
The continuation of the data taking with the BOREXINO detector.
Analysis of results of the calibration campaign with internal light sources.
Development of new position reconstruction algorithm for Borexino detector.
The study of day/night and seasonal variations of the solar neutrino flux.
Precise measurement of the Be-7 flux with total errors down 5%.
Improvement of the current results on the effective solar neutrino magnetic moment.
Limits on solar antineutrino flux and relic supernovae flux.
Participation in tests and assembly of the Daya Bay central detector.
Development of Monte Carlo software for cosmogenic background simulation in the Daya Bay experiment.
