Description
There are a few anomalies known to the modern neutrino physics that can not be described by the three-neutrino mixing and oscillation framework. Reactor neutrino experiments observe a deficit of anti-neutrino flux at a level of 2.6$\sigma$ with respect to the prediction. Gallium detectors for solar neutrinos observed a deficit of events from radioactive calibration sources of neutrino ($^{37}Ar$ and $^{51}Cr$) at 2.3$\sigma$ level. One of the possible explanations of the anomalies is an existence of one or more sterile neutrino states, which doesn’t interact weakly.
The next generation neutrino reactor experiment JUNO will use satellite detector TAO to make a precise measurement of antineutrino flux from Taishan Nuclear Power Plant. The baseline of 30 m to the reactor and unprecedented energy resolution enable the experiment to exclude four-neutrino mixing in the region of mass splittings of 10$^{-2}$ < $\Delta m^2_{41}$ < 10 eV$^2$.
The overview of the detector and results of the sensitivity analysis of the TAO will be presented in this poster.
