2 Beyond knowledge frontiers Relativistic path Quantum path High energies LHC: 7 TeV collisions now 14 TeV in near future Clean and high statistics SuperB: e + e - machine with target luminosity cm -2 s -1 at the (4S) (x50 more than in the past) 06/07/11 Assemblea di Sezione M. Villa 2

3 Physics programme in a nutshell Versatile flavour physics experiment Probe new physics in wide range of decays. Deviation from Standard Model can be used to identify structure of new physics. Clean experimental environment means clean signals in many modes. Best capability for precision CKM constraints of any existing/proposed experiment. Measure angles and sides of the bd and cu unitarity triangles. Measure other CKM matrix elements at cc threshold and using data. by Ciuchini 06/07/11 Assemblea di Sezione M. Villa 3
