From BABAR to the Future

The B Factories PEP-II and KEKB operating since 1999 have produced a rich harvest of beautiful and somehow intriguing experimental results in the flavor sector. After the discovery of the indirect (2001). and the direct (2004) CP violation [1-4] in the B sector, the present experimental situation is in a phase of precision measurements of sides and angles of the Unitarity Triangle, potentially able to produce more precise tests of CKM model. As well known, the CP violation accounted by CKM in the standard model fails in the explanation of amount of deficit of antimatter with respect to the matter in the universe. If we still assume CP as the origin of such a deficit, one should expect contribution coming from phases related to New Physics. Lepton Flavor Violation (LFV) in τ decay and in general rare τ and B decays would allow some evidence of New Physics. The status of B Factories measurements is reported here, together with ideas of a future facility operating at a luminosity ≥ 10³⁶cm²s^-1, much higher than the present B, Factories PEP-II and KEKB.
