Experimental Particle Physics
PhD University California at Santa Cruz, 1996
Professor Barberis’s research in experimental high energy physics is focused on the study of matter at the smallest distance scale. She is currently working on the DØ and CMS experiments.
As a member of the DØ experiment at the Tevatron Collider at Fermilab, Prof. Barberis is currently studying collisions of protons and antiprotons at a center of mass energy of 2 TeV. At such energy scale, the fundamental constituents in the protons and antiprotons interact to produce other massive states, such as the Top quark, discovered by the Tevatron Collider experiments, DØ and CDF, in 1995. The focus of Prof. Barberis work has been the detailed study of top quark properties, electroweak interactions, and the search for the mechanism responsible for the generation of all particles masses (in the Standard Model of particle physics, the Higgs field).On the DØ experiment, Prof. Barberis led the effort to design and implement the software system which reconstructs events recorderd by the Silicon Microstrip tracker, and co-lead the Top quark physics analysis group.
On the CMS experiment at the LHC collider at CERN, Prof. Barberis is studying collisions of protons at the world’s highest center of mass energy (7 TeV in 2011). Prof. Barberis is working on searches for new physics beyond the Standard Model and is co-leading the Exotica physics analysis group that studies Leptons+jets signatures (production of leptoquarks and similar signatures. On the CMS experiment, Prof. Barberis is working on the calibration of the End-Cap Muon chambers and on muon reconstruction software.
Before joining the DØ Experiment, Prof. Barberis worked on the ZEUS experiment at DESY in Hamburg, Germany. The ZEUS experiment used the high energy collisions of electrons and protons to perform detailed studies of the structure of the proton.
