The Higgs cant live without it

• A Higgs (or Higgs-like) particle is required in
  the SM
• Not just a mathematical trick, but effects
  measurable processes
• Eg

Contribution which grows like me2s cancels
between Higgs diagram and others
ee- ? WW-
LEP EWWG, hep-ex/0312023

Constraints on Higgs boson H0SM

• MH (summer 2006)
• c2 minimum
• 85 GeV
• Direct Search LEP
• gt 114 GeV _at_ 95 C.L.
• Precision EW LEP direct search limit
• lt 199 GeV _at_ 95 C.L.

EW Fits MH free Param. Data from LEP, SLD,
Tevatron

• Complete the SM
• Find H0SM?
• Beyond the SM _at_ 1TeV
• New symmetries, compositeness , ...
• Strongly motivated to avoid MH fine-tuning

Next projects

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

6
Terascale Detector WG

• Discussed overall SLHC (ATLAS upgrade) and ILC
  detector plans
• Overviews by Dean Karlen and Nigel Hessey (ATLAS
  upgrade coordinator)
• Emphasis on Canadian (potential) contributions
• Reviewed detector mechanical design needs,
  assessed commonalities
• Reviewed detector electronics design needs,
  assessed commonalities
• Did not discuss, eg, renewal of electronics group
  basic infrastructure, computing hardware renewal,
  accelerator contributions in detail
• But this is still essential to our program and
  needs 5YP inclusion!

Cdn ATLAS Upgrade Projects

• Forward Calorimetry at high rates
• Significant potential problems with (largely Cdn
  built) ATLAS calorimeters at SLHC
• Boiling liquid argon? Ion mobility at high
  rates?
• Possible solution
• New high rate calorimeter shielding LAr FCAL
• Hadronic Endcap (HEC) electronics
• Cdn-built detector may have pre-amp radiation
  failure
• RD on new technologies now, ready for
  replacement
• Tracking
• Complete ATLAS tracker replacement needed after
  3 years of high rate data taking
• Strong Canadian leadership in diamond pixel
  detectors
• Strong Canadian interest in tracking front-end
  readout

8
Cdn ILC Detector Projects

• Time Projection Chamber
• Strong Cdn leadership for ILC TPC, synergies with
  T2K
• Endplate sections with readout (GEM/MicroMegas)
• Calibration system, gas system
• Overall system integration engineering
• Readout electronics
• DAQ
• Hadronic calorimetry
• Fine grain Scintillator SiPM readout
• Allows particle ID, matching to tracking
  detectors with overlap suppression
• Best resolution from full energy-flow techniques

Other notes

• Assume all production people from NSERC
• Here just TRIUMF infrastructure for design,
  development
• Did not discuss, eg, renewal of electronics group
  basic infrastructure, computing hardware renewal,
  accelerator contributions (? plenary) in detail
• But this is still essential to our program and
  needs 5YP inclusion!
• Recommend review of other infrastructure (eg,
  clean rooms) considering detector development
  needs
• Also clarify mechanisms for allocation of
  personnel / time, especially for outside users
• Also discussed central role of TRIUMF in Geant4
  support
• With 3 FTE in this area, could be world leading
  contributor
• Short term, with 1.75 FTE, leader in ILC/SLHC
  simulation detector design
• White-paper draft by end of August
