  1. 2nd Open Meeting of the Super-KEKB Collaboration March 17-19, 2009 3-gokan, Seminar Hall KEK

  2. Welcome !

  3. Super-KEKB Collaboration • Long way to come here • Beyond 1034 e+e- workshop (2000.6) • 1st Super-KEKB workshop (2001.8)6th (2004.11) • Joint Super B Factory workshop in Hawaii (2004.1)2nd (2005.4) • B Factories and New Measurements (2006.9)3rd (2008.1) • 1st Open meeting for the proto-collaboration (2008.3) • 2nd Open meeting for the proto-collaboration (2008.7) • 1st Open meeting of the Super-KEKB collaboration (2008.12) E.O.I from 42 inst. 1st IB meeting today Chair: Leo Piilonen Let’s take a picture like this with Kobayashi-san.

  4. LHC Energy frontier experiments LHC, ILC, … KEKB upgrade Higgs, SUSY, Dark matter, New understanding of space-time… ILC n exp., m LFV, t LFV, gm-2, 0nbb… B Factories, LHCb, K exp., nEDM etc. Neutrino mixing/masses, Lepton number non-conservation… CP asymmetry, Baryogenesis, Left-right symmetry, New sources of flavor mixing… J-PARC High Energy Physics in the Next Decade New particles and new interactions Three approaches to New Physics Lepton physics Quark flavor physics

  5. operation & completion of 1st goal J-PARC power upgrade upgrading to Super-KEKB KEKB operation & upgrade Photon Factory continue R&D and compact ERL ERL R&D Summary of KEK Roadmap 2007 2008 2009 2010 2011 2012 construction 1st results operation LHC LHC upgrade TDP1 ILC R&D lots and lots of R&D’s TDP2

  6. Luminosity Prospect 50ab-1 by ~2020 X50 present Physics with O(1010) B & t also D L~8x1035 cm-2s-1 3year shutdown for upgrade

  7. Physics Reach at Super-KEKB/Belle Upper limits • Sharpening your eyes where to look • Hints for NP workshop Search for H± in B→tn 50ab-1 assume 5s discovery CP asymmetry in B→KKK, fK and h’K ■　 　●　 　　　　★ 0.3 X10-9 (3s discovery lim.) 0.1 Deviation from SM Present exp. limits 0.03 CKM at 50ab-1 Integ. Lum.（ ab-1） 5ab-1 Reach of B factories 50ab-1 0.01 Upgraded KEKB 1 10 100 Physics at Super B Factory (hep-ex/0406071) being updated. Integ. luminosity (ab-1)

  8. Crab crossing New IR b*y = σz = 3 mm SuperKEKB Crab cavities installed and undergoing testing in beam e+ 9.4 A e- 4.1 A Studies also for low-emittance scheme has started. Dampiing ring The superconducting cavities will be upgraded to absorb more higher-order mode power up to 50 kW. The state-of-art ARES copper cavities will be upgraded with higher energy storage ratio to support higher current. Higher current More RF New vacuum system + Linac upgrade The beam pipes and all vacuum components will be replaced with higher-current design. will reach 8 × 1035 cm-2s-1

  9. Super-Belle (Baseline) ECL Wave sampling + pure CsI crystal(endcap) PID Threshold Aerogel + TOF →　TOP + Aerogel-RICH KL/m detection RPC → Scintillator +SiPM(endcap) Final design ? How do we decide, and when ? CDC Super small cell Longer lever arm New Dead time free readout and high speed computing systems SVD 4-lyr DSSD → 2-lyr. DEPFET pixel + 4-lyr DSSD

  10. Time Line • Near-term plan (preliminary) • Detector proposals (by summer 2009). • The final detector design by Dec. 2009. 2009 2010 2008 1 2 3 4 5 6 7 8 9 10 11 12 1 2 3 10 11 12 KEKB operation Internal review Detector proposals We need make clear the Time line / Milestone (also for accelerator design) Kick-off meeting (Dec 08) TDR Actions to invite new collaborators

  11. We must get ready before the G-Light ! • Accelerator • High current scheme or Low emittance scheme • Detector • Finalization of detector design • Organization • Collaboration name ? • Funding • Phyiscs Photodetector for E-PID Need determine the time line

  12. Enjoy !
