FInal Report: DE-FG02-04ER41310 "Elementary Particle Physics"
vATLAS and the LHC are delivering on the promise of discovery physics at the high energy frontier. Using 4.8 fb^-1 of 2011 √s=7 TeV data and the first 5.8 fb?1 of 2012 √s=8 TeV data, ATLAS published the observation of a new particle with a mass of 126 GeV with a significance of 5.9σ that is compatible with a Standard Model (SM) Higgs. The LHC is outperforming intial projections for the 2012 run, and ATLAS is on track to integrate ~20 fb^(-1) of proton-proton collisions in 2012 before Long Shutdown 1 (LS1) begins in Spring 2013. University of Texas at Dallas (UTD) physicists will complete work on two ATLAS analyses this fall. The first is the search for the gauge bosons of a hypothesized dark sector. For 2011 data, UTD is responsible for the ?dark photon?search in the electron-jet channel, and we are looking forward to an expanded leadership role in the dark photon search using the full 2012 data set. Our second analysis interest is the study of X/Y/Z exotic states having cc content, which builds on our experience in this field from the BABAR experiment After completing a measurement of the Xc(3872) production cross section this fall, wemore »
