Precise measurement of theta13 at Daya Bay
Abstract
The Daya Bay Reactor Neutrino Experiment is designed to determine the yet unknown neutrino mixing angle theta13 by measuring the disappearance of electron antineutrinos from several nuclear reactor cores, using multiple underground detectors at different baselines to minimize systematic errors and to suppress the cosmogenic background. The civil construction has begun since October 2007, enabling first commissioning data in 2009, and full data taking will begin in late 2010. The planned sensitivity in sin2 (2theta13) of better than 0.01 at 90% CL will be achieved in three years of data-taking. I will present an overview and current status of the experiment.
