23. Time-reversal violation and the origin of matter in the Universe

Prof. Antonio Masiero (Universita' di Padova)

Plenary

In the plasma of particles of the primordial Universe it is expected that matter and antimatter were present in equal amount. To dynamically develop a matter-antimatter asymmetry starting from such a symmetrical situation, a necessary condition is that CP is violated. In local quantum field theories CP violation is always accompanied by the same amount of time-reversal violation. Interestingly...

24. Direct observation of time-reversal violation in B0 decays

Invited

The B factories have established with great accuracy the violation of the CP symmetry in the B system. However, no direct observation of time-reversal violation had been performed prior to the work, recently published by the BABAR Collaboration, discussed in the present talk. The quantum entanglement of B-Bbar pairs produced in the decay of the Y(4S) resonance at the PEP-II asymmetric B...
