Gaosong Li (Shanghai Jiao Tong University) – "Daya Bay Experiment"

January 26, 2016 @ 4:00 pm - 5:00 pm

The Daya Bay Reactor Neutrino Experiment is designed to measure the neutrino mixing angle with unprecedented precision. The experiment utilizes multiple pairs of identical antineutrino detectors (ADs) at different baselines from three pairs of reactor cores to minimize systematic uncertainties. In 2012, Daya Bay made the first definitive measurement of a non-zero value for $\theta_{13}$ using the first 55 days of data collected with six ADs by measuring the antineutrino rate deficit. With the final two ADs installed, Daya Bay resumed data taking in full 8-AD configuration in late 2012. More than 1 (0.15) million electron antineutrino candidates had been collected with the near (far) site detectors by the end of 2013, significantly improving the precision on . In addition to precision measurement of neutrino oscillation parameters, analyses exploring various other physics potential are carried out.
In this talk, I will focus on the calibration system. I will present calibration related works I have been working on to improve the detector absolute efficiency and neutrino oscillation analysis. I will also present the results on neutrino oscillation parameters from an independent analysis.
