  1. SuperBa few notes G.Piredda Oct 6th 2006

  2. The physics case See for example: The Discovery Potential of a Super B Factory (Slac-R-709) Letter of Intent for KEK Super B Factory ( KEK Report 2004-4 ) Physics at Super B Factory ( hep-ex/0406071 ) At the URL : www.pi.infn.it/SuperB you can find documents and links to documents In addition the case was discussed in the CERN series of workshops organized by M.Mangano and T.Hurth of the Cern Theory division Flavour Physics in the era of LHC The first 3 worksops in Nov 2006, Feb 2006, May 2006 The May workshop included a special session devoted to High intensity, High luminosity flavour experiments with a comparison of the existing projects as SuperB, SuperKEKB and LHCb . The fourth CERN meeting will be held in october 10-12,2006

  3. The Machine Requirements • Peak luminosity at Y4s > 1036 • Geometrical acceptance> 99% • Background in the detector < present background in BaBar and Belle • Narrow beams and low bkgd allowing better • vertexing • Large Synergy with ILC. • Wall power <<50MW • Operation at the same time of LHC and before ILC. EVALUATE (cost/benefit also compared to the main physics program): • Possible operations in special runs at lower energy as SuperTauCharm • Possibility of one polarized beam for studying asymmetries due to T odd observables in tau decay.

  4. Defined a parameters set based on ILC-like parameters • Same DR emittances • Same DR bunch length • Same DR bunch charges • Same DR damping time • Same ILC-IP betas • Crossing Angle and Crab Waist to minimize BB blowup

  5. Simplified SuperB layout Crossing angle = 2*25 mrad ILC ring & ILC FF

  6. Crabbed waist

  7. From the 3rd SuperB Workshop (June )… Since beginning of SuperB International Study Group the goal was clear: Study physics case, machine and detector for a Super Flavor Factory with a luminosity higher than 1036, to study physics in b, c and t sectors. Prepare by the end of 2006 a Conceptual Design Report “CDR” to be delivered to the President of INFN and presented to the International Community. Events: July23-26 : Meeting at ITEP Moscow Presentations on Super KEKB and on SuperB projects followed by a round table …to the fourth one (November) Finalize the machine design Complete the detector design Review the various Physics Chapters Write everything up, Make the Editorial Board of the Conceptual Design Report

  8. The Site Site of SuperB is not defined and will remain undefined for quite a while. With present parameter choice the SuperB can reuse almost all the components of PEP-II. It can be located in a tunnel of 6Km, 3Km or 2 Km. Possible existing locations: Hamburg-Desy (Fermilab?) KEK Slac New site?? at the moment this is our first choice!

  9. Possible site: Tor Vergata campusRing circumference: 3. to 2.2 Km O 0.7Km O 1.0Km
