TL;DR: A dip in the L/E distribution was observed in the data, as predicted from the sinusoidal flavor transition probability of neutrino oscillation, which constrained nu(micro)<-->nu(tau) neutrinos oscillation parameters.

TL;DR: In this article, the neutrino oscillations were detected in coincidence with the expected arrival time of the beam in the 22.5kt fiducial volume of Super-Kamiokande, the far detector at 250 km distance.

Resolving the neutrino mass hierarchy and CP degeneracy by two identical detectors with different baselines
TL;DR: In this paper, the authors explore the possibility of the simultaneous determination of neutrino mass hierarchy and the CP violating phase by using two identical detectors placed at different baseline distances, and demonstrate that the two-detector complex with each fiducial volume of 0.27 Mton has a potential of resolving the neutrinos mass hierarchy up to sin{sup 2}2{theta}{sub 13}>0.03 (0.055) at 2{sigma} (3{ sigma}) C.L.
