  1. Report from the SuperB IRC John Dainton Cockcroft Institute and Department of Physics University of Liverpool, UK

  2. International Review Committee ●assembled in July 2008 by INFN - membership Hiroaki Aihara, JBD (chair), Rolf Heuer (to Nov 2007), Young Kee Kim, Jacques Lefrançois, Antonio Masiero, Steve Myers (for April 2008), Tatsuya Nakada (RECFA from April 2008), Daniel Schulte, Abe Seiden (wisdom, expertise, experience … and a chair!) - assess how progress recorded in CDR (and subsequently) is geared towards a timely TDR report to INFN

  3. IRC Schedule ●schedule to date - meeting Roma July 2007 following your CDR first discussion with SuperB senior management planning with INFN/SuperB for review steps - meeting Frascati November 2007 detailed physics discussion with SuperB group → suggestions, clarification, IRC objectives first discussion of machine run through of detector

  4. IRC Schedule ●schedule to date (continued) - meeting Roma April 2008 report on progress with beam waist tests detailed discussion of machine update on physics progress update on other issues IRC progressing short report (R)ECFA representation added to IRC - completion of first (short) report → INFN May 2008 Thank you ●throughout much help from and interaction with SuperB and INFN (including excellent hospitality)

  5. IRC Methodology ●method - read CDR (and then rather easily forget the detail in an impressive document!) - clear up misunderstandings with SuperB (July 2007) and define procedures towards a first assessment - in detail interaction with SuperB group → bring IRC input as questions and suggestions → SuperB physics workshop January 2008 - follow up on physics and detector (April 2008) response to IRC suggestions and questions detailed discussion of machine (incl. waist tests) → first report

  6. IRC First report ●5 pages + 2 references • Introduction and Context • Physics • Experiment • Machine • Conclusion

  7. IRC First report • Introduction and Context ● explanation of SuperB: 1036 cm-2s-1e+e- ● context: - step change beyond SuperKEKB (2×1035) - 75 ab-1 per “cycle” (5 years) - latter half of 2nd decade of 21st century - > 10 fb-1 from LHCb - aggressive timescale (in parallel with SuperLHCb ?)

  8. IRC First report • Physics ● breadth including - otherwise impossible - hither(then)to unprecedented precision -b-quark -τ-physics -c-quark - LFV - new states: hybrids, molecules, tetraquarks

  9. IRC First report ● examples to illustrate impact on fundamental questions in SUSY physics era - “golden” and leptonic B-decay - LFV -c-decay oscillations (sensitivity to soft SUSY breaking) + anticipated lattice • Is the observed SUSY manifestation due to supergravity, to gauge mediation, to anomaly mediation, or to some other mechanism? • Is one concerned with a minimal SUSY extension of the SM (MSSM) or a non-minimal one?

  10. IRC First report ● unique sensitivity to flavour in new physics - indirect energy reach < ~ 10 TeV ? ● new flavour physics beyond few TeV - SuperB = (indirect) energy frontier → discovery machine ● continue evaluation to establish physics specification

  11. IRC First report • Experiment ● substantial experience + components ● machine-detector interface - crab waist - small bunch dimension - polarisation ● continue (and accelerate) necessary R&D ● particular attention to “moth-balling” components for years

  12. IRC First report 4. Machine ● hugely ambitious and hugely challenging ● step-change in lumi pushes very many aspects of cutting-edge accelerator physics and technology beyond present by factors and into unknown → contingency ? → inclusive design simulation ● procure and protect PEP2 components wherever any future possibility of use ● huge amount of challenging work requires expansion of FTE staff to meet schedule ● MAC now essential

  13. IRC First report • Conclusion ● recommend strongly continuation of work for 1036 cm-2 s-1 asymmetric e+e- collider ● even more concerted effort to fully evaluate physics potential ↔ machine specifications ● major design program to establish credibility of machine now critical← showstoppers? ● MAC now essential ● preservation of detectors PEP2 components increasing global involvement if timescale for a TDR is to be met
