The ATLAS Experiment; to the Heart of MatterThe SFU Experimental High-Energy Particle Physics Group

• 3 faculty members, 3 postdocs, 7-8 graduate students, and N undergraduates

• Search for the fundamental constituents of matter and their interactions

• ATLAS: Experiment at CERN in Geneva, Switzerland to study proton-proton collisions at the highest energies ever achieved in the laboratory

• How do subatomic particles get their mass? Higgs boson• Top quark studies• Is there Physics Beyond the Standard Model?

- Supersymmetry - Quark substructure - Extra dimensions - Grand Unified Theory

• Experiment/Analysis Support: - Liquid Argon Calorimetry (Jet-Energy Scale) - Tau lepton identification - Worldwide Computing Grid - Global Data Quality Monitoring

Discovery of a SM-Higgs-like Boson!!

Postdoc @ CERN:- Jet-Energy Scale what really happens when a high-energy particle hits the calorimeter? - Top-quark cross sections

Mike Vetterli (Joint with TRIUMF)

LAr Calorimetry: measure the energy of theparticles coming from the proton-proton collisions

Jet PhysicsQuark substructure

MSc student:- Jet-Energy Scale in Z+jet Events - Response @ low energy in 2011 data - quark vs gluon jet response

MSc student:- Jet-Energy Scale in Dijet Events - how does the calorimeter response depend on whether the jet originated from a quark or a gluon?

ATLAS-Canada Tier-1 Computing Centre

One of only 10 Tier-1 centres in the Worldwide

LHC Computing Grid (WLCG)

MV is the Project Leader

The Tier-1 centre currently consists of: - 5,000 cores in 554 nodes - 7,570 TB of disk - 5,500 TB of tape (robotic silo) - ≈ 50 Grid computing servers

ATLAS Publications Committee

I am the deputy-chair of the ATLAS Publications CommitteeThis committee is charged with organizing the review of all ATLAS publications (papers & scientific notes), as well as the final vetting of the documents.I will be the chair of PubCom next year (sabbatical at CERN)

Essentially in the last two years:- 186 Journal Papers

(a large number of them Letters)- 391 Scientific Notes

10 papers/mo
