The ATLAS Experiment; to the Heart of Matter The 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!! 47 papers already 25 more submitted

CERN: - Jet-Energy Scale what really happens when a high-energy particle hits the calorimeter? - Top-quark cross sections Mike Vetterli Mike Vetterli (Joint with TRIUMF) LAr Calorimetry: measure the energy of the particles coming from the proton-proton collisions Jet Physics Quark substructure MSc student: - Jet-Energy Scale in Z+jet Events - 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 47 papers already 25 more submitted I am the deputy-chair of the ATLAS Publications Committee This 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) Scientific Notes 10 papers/mo nth Mar 2010 Aug 2012
