  1. PP Roadmap The PPAP How it handles its role The Particle Physics Programme and the RoadMap SC Meeting, 15 Nov 2005

  2. PPAP Official Terms of Reference • A prioritised long-term strategy for particle physics • Advise on the Facilities required to deliver that strategy • Review the success of PPARC in meeting that strategy • Report to the Science Committee • Provide input for the annual Road Map update and the SC’s Strategy discussions • Consult the community SC Meeting, 15 Nov 2005

  3. Current Membership Peter Dornan (Chair) Giles Barr John Dainton Val Gibson Nigel Glover Tim Morris Franz Muheim Dan Tovey Peter Sharp Ex-officio Dave Charlton –co-Chair PPGP Steve King – co-Chair PPGP John Wormersly – Director PPD, CCLRC Ken Peach – co-Chair CERN Council Strategy Group PP Council Members Brian Foster John Ellis SC Meeting, 15 Nov 2005

  4. Items Discussed so far • Theory Topics - Strings, Lattice QCD, Phenomenology • LHC - ATLAS, CMS, LHCb, ALICE, Diffractive Production, SLHC • Linear Collider - Accelerator R&D – Sub-TeV, CLIC, Detector R&D - LCFI, CALICE, Physics • Neutrino Physics - SuperBeam – T2K, Double Beta Decay - SuperNEMO, COBRA, Reactor Experments – Braidwood, • Neutrino Factory, MICE • Tevatron - CDF, D0 • B-Factory - Babar, Super B-Factory • Future CERN Fixed Target programme • Detectors & Future Technology • E-Science - GridPP2, LCG-2 SC Meeting, 15 Nov 2005

  5. Involving the Community • Vital – but far from trivial • The role of the PPAP as a conduit between community and PPARC/SC has still to be established • Experimenting with individual visits to groups • also production of ‘Discussion Papers’ on major topics to elicit feedback from the community • and then produce PPAP Strategy Documents SC Meeting, 15 Nov 2005

  6. University Visits • So far fewer than I had hoped • However better than 1 per year! • Glasgow & Edinburgh • Nigel Glover, Kim Dollimore, pjd - Feb 15 • Manchester & Sheffield • Tony Doyle, pjd - May 12/13 • Response has been positive • More are planned SC Meeting, 15 Nov 2005

  7. PPAP Policy Documents • To summarise the views of the PPAP on the major issues • - after discussions in the PPAP and input from the community. • Two are in production • Linear Collider - coordinator - Franz Muheim • Neutrino Physics - coordinator - Giles Barr • Aim for Jan/Feb 2006 • In time to provide input to the CERN Council Strategy Review SC Meeting, 15 Nov 2005

  8. The PP Programme • The Primary Goal is surely • What is the Physics Beyond the Standard Model • This used to be ‘The Theory of Everything’ • But we are more circumspect now This involves detailed probing ofThe Standard Model And there are other Goals such as The Structure of Hadrons And it may be necessary to understand this much better to progress on the Primary Goal SC Meeting, 15 Nov 2005

  9. Major Themes Beyond the SM How good is the SM? Is there solution to the hierarchy problem? Is there low energy SUSY? Can we unify all interactions?, including gravity? Only 3 Generations?, Do protons decay?, More than 4 space-time dimensions? Origin of Mass Is the Higgs mechanism correct? Are there other mass generating methods?, Structure of the Scalar sector? One or more (or zero) Higgs bosons? Matter- Antimatter Asymmetry Does SM describe CP in the quark sector? What BSM physics can give CP violation, Is there CP violation in the lepton sector? SC Meeting, 15 Nov 2005

  10. Major Themes (2) Neutrinos/Leptons Are neutrinos Majorana or Dirac? Consequences of neutrino oscillation? Just 3 neutrinos? Absolute neutrino mass scale? Cosmological consequences of neutrino mass? Is lepton flavour violated in the charged sector? Is lepton number a good quantum number? Properties of the Strong Interaction How are quarks & gluons bound to form hadrons? Can we predict the hadronic spectrum? Are there exotic states? Is there a quark gluon plasma? Technical Advances Accelerators, Detectors, Electronics, Software SC Meeting, 15 Nov 2005

  11. Tools Experimental Discovery Physics Leptonic Physics Flavour Physics & CP Violation Precision Measurements Hadronic Physics Theoretical Phenomenological Modelling String Theory, M Theory Lattice QCD SC Meeting, 15 Nov 2005

  12. Experimental Programme SC Meeting, 15 Nov 2005

  13. SC Meeting, 15 Nov 2005

  14. SC Meeting, 15 Nov 2005

  15. SC Meeting, 15 Nov 2005

  16. SC Meeting, 15 Nov 2005

  17. SC Meeting, 15 Nov 2005

  18. Time Scales & Prioritisation Many of Following timescales are speculative - and priorities refer to the future SC Meeting, 15 Nov 2005

  19. Discovery Physics SC Meeting, 15 Nov 2005

  20. Leptonic Physics SC Meeting, 15 Nov 2005

  21. Flavour Physics & CP Violation SC Meeting, 15 Nov 2005

  22. Latest Results from D0 on Dms So CDF/D0 priority for heavy flavour results should be raised. They are now producing significant results in the Bs and b-baryon systems SC Meeting, 15 Nov 2005

  23. Hadronic Physics SC Meeting, 15 Nov 2005

  24. Technical R&D SC Meeting, 15 Nov 2005

  25. Theory The community is expanding at a greater rate than the number of PDRA’s Phenomenology Very successful recently - but UK still lacking in the area of neutrino phenomenology Strings, M-Theory UK second only to US - perhaps the best approach to BSM? - desire to establish a ‘Strings Institute’ Lattice QCD UK now has fastest machine, QCDOC, some excellent results recently. UKQCD is widely recognised as world-leading Quantum Field Theory Still a substantial effort in this area SC Meeting, 15 Nov 2005

  26. SC Meeting, 15 Nov 2005

  27. Phenomenology • Enormously important to maintain a strong phenomenological base in the UK. • Now much stronger than it was 10 years ago • Liaison with the experimental community is now very good SC Meeting, 15 Nov 2005

  28. Comments – Experiment Heavy Ions UK activity is small relative to other countries, Why? EDM Experiments Electron & Neutron - UK very strong - Beautiful experiments - speculative but could be sensational. Good that the UK supports such activities at a low level. Rare Decays Kaon, Muon – why such little UK activity? m -> e could be the next major discovery? K -> pnn provides independent determination of the unitarity triangle Super B-Factory Probably will be one in Japan - should it be in the UK Roadmap? So far no great interest - but if CP violation from penguins is different from CP violation from trees………… SC Meeting, 15 Nov 2005

  29. LHC Exploitation of the LHC Investment is the No. 1 Priority but there are many questions - the computing needs, personnel & machines - completion of the day-1 detectors - ‘minor’ upgrades over the next ~5 years to improve performance to replace damaged/faulty equipment SLHC Luminosity of 1035 by 2014? Requires substantial R&D - but exploitation must take preference over upgrades & R&D SC Meeting, 15 Nov 2005

  30. The Linear Collider (1) • A Vital Machine – but the future is hard to predict • Impressive progress since the decision for the cold technology • An Optimistic Scenario for the ILC • Decision by 2010, Data in 2016 • Expts & Machine to be designed by 2010 - • Relevance of CLIC? • UK should actively engage in the development of CLIC technology • Accelerator Centres? SC Meeting, 15 Nov 2005

  31. Linear Collider (2) • The UK must have a leading role • In the accelerator • LCABD - Beam Delivery, Beam Monitoring • Major Industrial Activity badly needed • Accelerator Centres Role? • Other countries are moving fast • In the Detectors • Going well - Vertex Detection (LCFI), Calorimetry (CALICE) • In the physics planning • Satisfactory • In the politics • Good SC Meeting, 15 Nov 2005

  32. The Neutrino Programme • Neutrino Related Activity is now expanding rapidly • MINOS has started taking data • Seed Corn Funds have been requested for Superbeam,T2K, and Neutrinoless Double Beta, Super-NEMO • Assuming success both have large programmes ahead • An SoI for a reactor experiment at Braidwood has been submitted • In addition SNO continues and there is a small UK participation in KATRIN • MICE is now approved for Phase-1 by Gateway, PPARC and CCLRC • Many Opportunities for the Future • The UK can (and should) have a big influence SC Meeting, 15 Nov 2005

  33. Future Neutrino Opportunities • Neutrino Detectors - Here there is minimal UK activity • They need to be very very large & affordable • Huge Calorimeters - with magnetic field? • Water Cerenkov • Liquid Argon a la ICARUS • Must they be underground • Neutrino Beams - Here there is considerable UK activity • High Powered SuperBeams • Beta Beams • Neutrino Factory • International Scoping Study for a future neutrino complex • UK Initiative – Launched June 2005 • - will examine physics reach – possible accelerators – potential detectors • There is a real possibility that a Neutrino Factory could be in the UK SC Meeting, 15 Nov 2005

  34. Neutrino Factory at RAL SC Meeting, 15 Nov 2005

  35. Summary • The next 15 years promises for Particle Physics • Many Opportunities • Much Excitement • But we need to be proactive to take advantage • Must maintain and strengthen out International Position • The PPAP will help to generate a viable strategy to justify the necessary resources SC Meeting, 15 Nov 2005
