    Latest results from Daya Bay

    Résumé : The Daya Bay Reactor Neutrino Experiment consists of eight functionnaly identical detectors placed underground at different baselines from six 2.9 GW reactor cores. In 2012, the experiment announced the discovery of a non-zero value of sin^2(2*Theta_13) with a significance better than 5 sigma, based on a dataset collected with six antineutrino detectors. In the summer of 2012, two addiotionnal detectors were installed and several millions-inverse beta decay (IBD) candidates have been collected since. With the largest sample of reactor antineutrinos ever collected to date with less background and better control of systematics, the measurement of the neutrino mixing angle Theta_13 has now reached an unprecedented precision below 4%.
