Plenary/section talk Particle physics: neutrino physics

### Speaker

Mr. Konstantin Treskov (Joint Institute for Nuclear Research)

### Description

Daya Bay was the first experiment to unambiguously measure a non-zero value of the $\theta_{13}$ mixing angle and the first reactor experiment to measure the $\Delta m^2_{32}$ mass splitting. The experiment includes eight identically designed detectors and six nuclear reactors at baselines ranging from 0.5 km to 1.6 km. A data set of nearly 4 million events has been collected over 1958 days of data taking, providing the most precise measurement of $\theta_{13}$ and a measurement of $\Delta m^2_{32}$ with a precision rivaling that from accelerator experiments. These measurements will be covered in this talk alongside with other significant results such as high-statistics measurement of the absolute reactor antineutrino flux and spectrum, as well as a search for light sterile neutrino mixing.
