Prospects of reactor neutrino experiments

Research output: Contribution to journalShort surveypeer-review


Since the energy of a reactor neutrino is a few MeV, all Δ m122, Δ m232 and Δ m132 oscillations are accessible by reactor neutrino experiments. KamLAND observed the Δ m122 oscillation and currently Double Chooz, RENO and Dayabay experiments are under construction aiming to detect Δ m132 + Δ m232 oscillation. There are still good prospects for future reactor neutrino experiments after them. For example, there is room to further improve sin2 2 θ13 accuracy at a baseline of ∼1.5 km, a very precise sin2 2 θ12 measurement and the determination of mass hierarchy may be possible at a baseline ∼50 km, and if KamLAND is enlarged to the SuperKamiokande size, better measurement of Δ m122 and sin2 2 θ12 will be anticipated. It is important to take into account such possibilities when planning future neutrino program after θ13 is measured by current experiments.
