High-Energy Physics with the ATLAS Experiment at the CERN Large Hadron Collider
My research is in the field of experimental high-energy physics (HEP). The goal of HEP is to uncover the basic building blocks of nature and the forces between them. In our current understanding of nature, called the “Standard Model”, the building blocks are quarks and leptons, while the forces are mediated by gauge bosons. The focus of my current research is the ATLAS experiment at the CERN Large Hadron Collider. The BU group has used ATLAS data to measure Standard Model processes (W and Z cross sections, WWW final states, production of top quarks) and to search for new physics (new gauge bosons (W’ and Z’), new strongly interacting particles called “technihadrons”, vector like quarks, and dark matter).

The ATLAS Experiment at CERN
The ATLAS experiment is a large detector system developed by a collaboration of physicists from around the world to study very-high-energy proton-proton interactions at the Large Hadron Collider (LHC) at CERN, a laboratory for high energy physics near Geneva, Switzerland. Boston University personnel were involved in the construction and installation of the muon detectors for ATLAS. The detectors occupy a region the size of a five-story building and measure the trajectories of muons in a magnetic field with a precision of better than 1/10 of a millimeter. This permits precise determination of the muon momentum which is an important ingredient in searches for new phenomena at the TeV energy scale. Boston University has also played a leading role in the development of computing and analysis tools.
