Results and Prospects from the Daya Bay Reactor Neutrino Experiment

TL;DR

The Daya Bay experiment provides highly precise measurements of neutrino oscillation parameters, confirms results through multiple detection methods, and explores additional phenomena like sterile neutrinos and potential CPT violation.

Contribution

It presents the most precise measurements of sin^2 2θ13 and Δm^2_ee, and introduces independent verification using neutron capture on hydrogen, expanding the experimental analysis scope.

Findings

Precise measurement of sin^2 2θ13 and Δm^2_ee

Confirmation of results via neutron capture on hydrogen

Constraints on sterile neutrino existence

Abstract

The Daya Bay reactor experiment has reported the most precise measurement of sin$^{2}2\theta_{13}$ and $\Delta m^{2}_{ee}$ by using a data set with the fully constructed design of 8 antineutrino detectors (ADs). We also report on a new independent measurement of sin$^{2}2\theta_{13}$ from neutron capture on hydrogen, which confirms the results using gadolinium caputres. Several other analyses are also performed, including a measurements on the absolute reactor antineutrino flux and a search for light sterile neutrinos. Prospects for new analyses such as searching for CPT/LI violation at Daya Bay are ongoing.
