2. Talk outline Brief Physics case for SuperB Present SuperB project Status The tests in Frascati The machine design and the recent Machine Advisory committee report The detector and detector R&D SuperB and ILC synergy Next steps Conclusion

3. Flavour physics in the LHC era The main objective is to unravel the flavor structure of the New Physics and the mechanisms causing its specific pattern Very good sensitivity to NP thru CP violation asymmetries and rare decays Double-prong attack on the quark and lepton sectors 3 3

5. Is there a no-loose theorem? In the assumption of a MFV scenario, is the LHC mass range well covered? Is the sensitivity in the leptonic sector meaningful in the LHC era? –The answer is PROBABLY YES if you can integrate at least 75 ab -1 with a Super B machine This requires a luminosity in excess of 10 36 during 5 years

6. Present knowledge about NP obtained by B factories and Tevatron

7. A conversation between Flavour Physics, LHC and ILC When evidence is found for New Physics at the LHC, attention will turn to understanding the details – Is it SUSY? What type of symmetry breaking? – Is it extra dimensions? Are they warped? The ILC will eventually sharpen the picture by, for example, measuring slepton masses SuperB/LHCb will be crucial to an understanding of the flavor sector of any type of new physics –Is there charged lepton flavor violation? –Are there new CP phases ? –Is there a charged Higgs ? –Is there minimal flavor violation in the (s)quark sector? 7

8. What is needed to know, once SUSY is found!

10. Lepton flavor violation (LFV) Lepton flavor violation is unobservably small in the Standard Model Neutrino mixing proves that there is neutral LFV The next natural question is whether there is charged LFV? Will the neutrino pattern be repeated? –If so, then LFV will be largest in 3  2 transitions Best bets: 10

38. Conclusions for the machine The Super-B parameters are being optimized around 1 x 10 36. The team is addressing the Mini-MAC suggestions from the July meeting. IR present design is a strong basis on which to start adding subtle features. IR polarization (spin) rotators have now been added to the HER lattice. Polarization has changed the geometrical layout. Beam-beam and dynamic aperture calculations have started. The new lattice layouts show improvement. Beam loading and RF parameters have taken the next solid step. Looks acceptable. Planning for the Technical Design Report has started. The areas for further concentration: –Look for issues with the potential new site –Lattice emittance tuning and dynamic aperture –Vibration measurements and active damping for IR –Polarization geometry and tolerances –IR engineering –Next round of beam-beam interaction studies –Beam dynamics studies (ECI for e+ and ions for e-)

50. The next steps Next SuperB general meeting June 16-20 in Perugia –October 1-5 at SLAC –December in Frascati June 2009: encouraging statement from Italian governement is expected Bilateral MoUs to be signed between INFN and international partners Statement from CERN council reagrding SuperB as part of the European Strategy expected in September 2009 Intermediate document to be transmitted to Italian governement at the end of 2009 Groundbreaking start hoped in 2010, together with SPARC-X project TDR written : end 2010

51. Conclusions Flavor physics presents an very exciting opportunity to understand new physics uncovered at the LHC LCHb and SuperB factory are very complementary tools. A superb new idea to build a machine of unprecedented luminosity. Tests at DAFNE demonstrated the concept! Machine Advisory Committee endorsed the machine feasability. There is a real chance that a SuperB project be approved in Europe provided it is very vigorously pushed by the new Italian government TDR phase now in full steam, time to join! To be completed by end 2010 Important synergy with ILC key elements Expected first beams in 2015…. 51
