Utilizing Neutron Capture on Hydrogen to Measure Theta$_{13}$ at Daya Bay
ORAL
Abstract
The Daya Bay Reactor Neutrino Experiment has provided the most precise determination of the neutrino mixing angle, $\theta_{13}$. The precision of this determination is crucial for future measurements of CP violation in the lepton sector. Now, Daya Bay is performing a largely independent measurement of $\sin^{2}2\theta_{13}$ utilizing neutron capture on hydrogen. Previous results use six 20-ton Gd-loaded scintillating targets while the new measurement uses six additional 22-ton scintillating targets that are not Gd-loaded. This talk introduces the basic differences between the two determinations, including a discussion of their correlations. This talk also gives an illustration of how the new, statistically-independent measurement of $\sin^{2}2\theta_{13}$ is significantly systematically-independent, and is expected to improve the uncertainty from Daya Bay.
