Apart from the pd reaction also the scattering of antiprotons with transversal polarization PPY on deuterons with tensor polarization Pxz provides a null-test signal for time-reversal-invariance violating but parity conserving effects. Assuming that the time-reversal-invariance violating N̅N interaction contains the same operator structure as the NN interaction, we discuss the energy dependence of the null-test signal in p̅d scattering on the basis of a calculation within the spin-dependent Glauber theory at beam energies of 50-300 MeV.

In this letter we reinterpret and reanalyze the available data of the B-meson factories showing the existence of direct experimental evidence of time reversal invariance violation in B-mesons. This reinterpretation consists of using the available observables to define a new observable which, in a model-independent way and without assuming CPT invariance, compares a transition between a B0 and a here-defined Bα-state, with its time reversed transition. The observable then offers a direct way to probe time reversal invariance and it is therefore independent of any conclusion obtained from current experimental information on CP violation and CPT invariance. As far as we are concerned, this is the first direct evidence of time reversal invariance violation in B-mesons and also the first one obtained from decaying particles whose mean lifetime difference is negligible.
