Title: Time Reversal and CP Violations for Neutrino Oscillations in Matter Abstract: This is a repeat of the seminar given at T-2 July 26 for those P-25 members who could not make it. The seminar discusses our recent predictions of Time and CP violations via neutrino oscillations due to matter effects for experiments with different baselines and energies. For TRV a future experiment is proposed. For CPV experiments are very difficult.
