3 August 2007 McPherson --Terascale Detector Development TRIUMF Town Meeting 2

3 August 2007 McPherson --Terascale Detector Development TRIUMF Town Meeting 3 The Higgs: cant live without it u A Higgs (or Higgs-like) particle is required in the SM u Not just a mathematical trick, but effects measurable processes u Eg: LEP EWWG, hep-ex/ e + e - W + W - Contribution which grows like m e 2 s cancels between Higgs diagram and others

3 August 2007 McPherson --Terascale Detector Development TRIUMF Town Meeting 4 Constraints on Higgs boson H 0 SM EW Fits: MH free Param. Data from LEP, SLD, Tevatron u MH (summer 2006) 2 minimum: 2 minimum: u 85 GeV u Direct Search LEP: u > % C.L. u Precision EW + LEP direct search limit u < % C.L. Complete the SM: Find H 0 SM ? Find H 0 SM ? Beyond the 1TeV Beyond the 1TeV New symmetries, compositeness,... New symmetries, compositeness,... Strongly motivated to avoid MH fine-tuning Strongly motivated to avoid MH fine-tuning

3 August 2007 McPherson --Terascale Detector Development TRIUMF Town Meeting 5 Next projects u Requirements for light Higgs-like scalar very strong u Can only be discovered and studied with direct production u Indications for ~ TeV scale new physics compelling, but nature of new physics unknown u There is no substitute for pushing direct energy reach into the TeV regime u Can see this clearly by general constraints on new physics models which are dominated by high-energy collider results u Many more physics areas as well u Top Mass/BR, W/Z physics, Gauge couplings, QCD, heavy flavour physics, meson spectroscopy / exotics, tau physics, … u Two colliders of relevance to next TRIUMF 5YP u LHC: Large Hadron (p-p) Collider at CERN u ATLAS detector: major ongoing Canadian efforts u Major upgrades needed after ~ 3 years of full rate data-taking u ILC: International Linear (e + e - ) Collider

3 August 2007 McPherson --Terascale Detector Development TRIUMF Town Meeting 6 Terascale Detector WG u Discussed overall SLHC (ATLAS upgrade) and ILC detector plans u Overviews by Dean Karlen and Nigel Hessey (ATLAS upgrade coordinator) u Emphasis on Canadian (potential) contributions u Reviewed detector mechanical design needs, assessed commonalities u Reviewed detector electronics design needs, assessed commonalities u Did not discuss, eg, renewal of electronics group basic infrastructure, computing hardware renewal, accelerator contributions in detail u But this is still essential to our program and needs 5YP inclusion!

3 August 2007 McPherson --Terascale Detector Development TRIUMF Town Meeting 7 Cdn ATLAS Upgrade Projects u Forward Calorimetry at high rates u Significant potential problems with (largely Cdn built) ATLAS calorimeters at SLHC u Boiling liquid argon? Ion mobility at high rates? … u Possible solution: u New high rate calorimeter shielding LAr FCAL u Hadronic Endcap (HEC) electronics u Cdn-built detector may have pre-amp radiation failure u R&D on new technologies now, ready for replacement u Tracking u Complete ATLAS tracker replacement needed after ~ 3 years of high rate data taking u Strong Canadian leadership in diamond pixel detectors u Strong Canadian interest in tracking front-end readout

3 August 2007 McPherson --Terascale Detector Development TRIUMF Town Meeting 8 Cdn ILC Detector Projects u Time Projection Chamber u Strong Cdn leadership for ILC TPC, synergies with T2K u Endplate sections with readout (GEM/MicroMegas) u Calibration system, gas system u Overall system integration engineering u Readout electronics u DAQ u Hadronic calorimetry u Fine grain Scintillator + SiPM readout u Allows particle ID, matching to tracking detectors with overlap suppression u Best resolution from full energy-flow techniques
