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.
