Although all present tests of CPT invariance confirm this symmetry, impossed by any local quantum field theory with Lorentz invariance, it would be of great interest to observe Time Reversal Violation (TRV) directly in a single experiment, independent of CP, and as a genuine test, implying the interchange between in-states and out-states.
The only theoretical ingredient to perform this test...

We present recent results from the BABAR collaboration of measurements of CP violating B decays and the determination of the unitarity triangle.

Recent results on CP violation measurements in B decays from Belle
are reported. Thanks to large accumulated data sample, CP violation
in B decays in mixing-decay interference and direct CP-violation
are now firmly established.

The angular analysis of B -> V (-> P_1 P_2) l+ l- provides a rather large set of observables. They allow for tests
of electro-weak short distance couplings in the Standard Model and searches beyond. Moreover, the two
distinct regions of low- and high-dilepton invariant mass, which depend in a complimentary way on short
distance physics, can be treated systematically in power expansions....
