T-Violating Effects in Neutrino Oscillations with Three Flavors in Matter

We investigate the interplay of fundamental and matter-induced T-violating effects in three flavor neutrino oscillations in matter. In addition, we present an approximative analytical formula for the T-violating probability asymmetry valid for an arbitrary density profile. We also discuss some implications of the obtained results. Since there are no T-violating effects in the two flavor case, the T-violating probability asymmetry can, in principle, provide a way to measure theta_13 and Delta m_21^2. Finally, we apply our approximative analytical formula to different scenarios for neutrino factories using two layer matter density profiles. We also show for terrestial experiments that matter-induced T violation can safely be ignored and cannot hinder the determination of fundamental T violation.
