The Higgs: can’t live without it



A Higgs (or Higgs-like) particle is required in the SM
Not just a mathematical trick, but effects measurable
processes
Contribution which grows
Eg:
like me2s cancels between
e+e-  W+WHiggs diagram and others


 Complete the SM:
 Find H0SM?
Beyond the SM @ 1TeV
 New symmetries,
compositeness , ...
 Strongly motivated to
avoid MH fine-tuning

Next projects

Requirements for light Higgs-like scalar very strong


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


Can only be discovered and studied with direct production
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 (e+e-) Collider

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
 R&D 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

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

- as above
Other notes

Assume all production people from NSERC


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



Here: just TRIUMF infrastructure for design, development
With ~ 3 FTE in this area, could be world leading contributor
Short term, with ~ 1.75 FTE, leader in ILC/SLHC simulation detector design
