T, C, P, CP symmetries, Accidental symmetries (B, L conservation)

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...

T, C, P, CP symmetries, Accidental symmetries (B, L conservation)

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

T, C, P, CP symmetries, Accidental symmetries (B, L conservation)

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.

T, C, P, CP symmetries, Accidental symmetries (B, L conservation)

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....
