P J DornanSC Meeting, 15 Nov 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 also production of ‘Discussion Papers’ on major topics to elicit feedback from the community and then produce PPAP Strategy Documents and then produce PPAP Strategy Documents

P J DornanSC Meeting, 15 Nov 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

P J DornanSC Meeting, 15 Nov 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

P J DornanSC Meeting, 15 Nov 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 of The 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

P J DornanSC Meeting, 15 Nov 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?

P J DornanSC Meeting, 15 Nov 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

P J DornanSC Meeting, 15 Nov Theory The community is expanding at a greater rate than the number of PDRA’sPhenomenology 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

P J DornanSC Meeting, 15 Nov

P J DornanSC Meeting, 15 Nov 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 AreaPriorityComment SUSY, BSM 5 Vital for LHC exploitation. Improving in the UK but more is needed Neutrinos/leptons4 Major growth area internationally. Very weak in the UK and needs strengthening urgently Flavour CKM/CPV 4 Strong in the UK QCD4 Very strong in UK. MC work is particularly important and visible SM4 Necessary to find BSM, UK activity is low Lin Collider 4 UK making significant contributions

P J DornanSC Meeting, 15 Nov 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?  -> e could be the next major discovery? K ->  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…………

P J DornanSC Meeting, 15 Nov 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 equipmentSLHC Luminosity of by 2014? Requires substantial R&D - but exploitation must take preference over upgrades & R&D - but exploitation must take preference over upgrades & R&D

P J DornanSC Meeting, 15 Nov 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 Relevance of CLIC? UK should actively engage in the development of CLIC technology Accelerator Centres?

P J DornanSC Meeting, 15 Nov 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

P J DornanSC Meeting, 15 Nov 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

P J DornanSC Meeting, 15 Nov 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 will examine physics reach – possible accelerators – potential detectors There is a real possibility that a Neutrino Factory could be in the UK

P J DornanSC Meeting, 15 Nov Neutrino Factory at RAL

P J DornanSC Meeting, 15 Nov 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
