Daya Bay’s Latest Oscillation Results Using Neutron Captures on Gadolinium

Not scheduled


Olivia Dalager


The Daya Bay Reactor Neutrino Experiment was designed with the primary goal of precisely measuring the neutrino mixing parameter, $\theta_{13}$. Eight identically-designed gadolinium-doped liquid scintillator detectors located in three underground experimental halls measure the reactor antineutrino flux at different distances from six nuclear reactors. Daya Bay has acquired nearly 4 million inverse beta decay candidates using neutron capture on gadolinium, the largest reactor antineutrino sample in the world to date. In this poster, I will present a brief overview of the experiment and discuss the recent improvement of systematic uncertainties pertaining to the absolute energy response, cosmogenic background and spent nuclear fuel. I will show the latest oscillation results that include the most precise measurement of the $\theta_{13}$ neutrino-mixing angle in the world.
