Reactor antineutrino experiments
Year: 2014
Type: conference-paper
Abstract: Neutrinos are elementary particles in the standard model of particle physics. There are three flavors of neutrinos that oscillate among themselves. Their oscillation can be described by a 3×3 unitary matrix, containing three mixing angles θ 12 , θ 23 , θ 13 , and one CP phase. Both θ 12 and θ 23 are known from previous experiments. θ 13 was unknown just two years ago. The Daya Bay experiment gave the first definitive non-zero value in 2012. An improved measurement of the oscillation amplitude [Formula: see text] and the first direct measurement of the [Formula: see text] mass-squared difference [Formula: see text] were obtained recently. The large value of θ 13 boosts the next generation of reactor antineutrino experiments designed to determine the neutrino mass hierarchy, such as JUNO and RENO-50.
