Sažetak
We study the determination of neutrino mass hierarchy through neutrino experiments foreseen in the next ten years. The T2K neutrino oscillation experiment will start in 2009. In the experiment, the high intensity νµ beam from JHF is directed to Super-Kamiokande (SK) detector 295 km away. The NOνA (off axes neutrino oscillation) experiment is being planned, with the νµ beam from Fermi-Lab directed to a site 610 km away, which is 0, 7 and 14 milliradian off-axes. Both above experiments will measure νµ → νe oscillation probability. The Double-CHOOZ experiment under construction will detect νes emitted by nuclear reactors both through a near detector (150 m) and a far detector (1.05 km) to measure νe → νe survival probability. In this paper, we outline a procedure to determine the sign of ∆31 from the simulated data of the above experiments.
