T-violation search with very long baseline neutrino oscillation experiments
arXiv:hep-ph/9911258 · doi:10.1103/PhysRevD.62.073006
Abstract
We consider possibilities of observing T-violation effects in neutrino oscillation experiments with very long baseline (~ 10000 km) using low energy neutrino (~ several hundreds MeV). We show that the matter effect effectively changes only the first-second generation mixing angle, respecting solar neutrino deficits and atmospheric neutrino anomalies. The effective mixing of the first-second generation in the Earth grows up to maximum by resonance. This effect enables one to search T violation in case the first-second mixing angle is small. We discuss its implications to the observations of T-violation effects in long baseline experiments.
