## Ph.D. thesis

A search for new physics in high-mass ditau events in the ATLAS detector
July 2013

My graduate research as a student at the University of Pennsylvania, working with the ATLAS experiment at the Large Hadron Collider at CERN, was on the reconstruction and identification of hadronic tau decays, measuring the Z→ττ production cross section in proton-proton collisions at √s = 7 TeV, and searching for new physics in high-mass ditau events. You can download my thesis here or find it at CDS as CERN-THESIS-2013-075.
