Poster Neutrino oscillation

Description

The Daya Bay Reactor Neutrino Experiment was designed to make a precise measurement of the $\theta_{13}$ oscillation parameter and was the first experiment to measure its non-zero value with more than 5$\sigma$ significance. Antineutrinos are detected within the eight functionally identical detectors via inverse beta decays. These detectors are located in three underground experimental halls (two near, one far) at various baselines from six nuclear reactor cores. The relative measurement of the observed antineutrino rate and spectral shape at the different detectors allows to significantly suppress several key systematic uncertainties. In this poster, I will describe the oscillation analysis and present the newest results for $\sin^2(2\theta_{13})$ using a sample of reactor antineutrinos identified via neutron capture on hydrogen, which is largely independent from the analysis done with neutron capture on gadolinium.
