The ATLAS group at Northern Illinois University

ATLAS is one of the two general-purpose detectors getting ready to study proton-proton collisions at a center-of-mass energy of up to 14 TeV to be delivered by the Large Hadron Collider at CERN. Several members of the Experimental High Energy Physics Group at NIU participate in the ATLAS project. The ATLAS group at NIU currently consists of
The NIU group is engaged in several critical tasks in operations of the ATLAS detector, its planned upgrade, and high-priority physics analyses. Much of these activities are conducted in close collaboration with colleagues at the Argonne National Laboratory.

Detector operation

The NIU group is contributing to the running of the ATLAS experiment through the following tasks (* = current): In the past the team has contributed to In addition to offline development, maintenance, and support activities, team members also take detector and software operation shifts appropriate for their areas of involvement.

Detector upgrade

We are participating in the Fast Track Trigger (FTK) project to improve ATLAS' track-based triggering capabilities in the Phase 1 upgrade [Blazey, Burghgrave, Chakraborty, Yurkewicz].
Beyond that, a Phase 2 upgrade aims for a ten-fold increase in the average instantaneous luminosity. Extensive modifications to many parts of the detectors will be necessary to perform on par or better than the initial implementation despite the increased event rate. We have contributed to the simulation and algorithm development for the forward pixel tracker (disks) [Lima].

Physics analysis

The NIU team's main physics interests are in searches for physics beyond the Standard Model in production and decay of top quarks and studies of triple gauge coupling through WZ production at the LHC.

Other involvements

In relation to and extension of the above interests and activities, members of the group contribute, or have contributed, to several other tasks including
