Objective Operating at the highest energies of any particle accelerator, the Large Hadron Collider (LHC) will open new frontiers in the study of elementary particle physics. Analysis of the large data sets collected by the LHC¿s ATLAS detector will help to address longstanding gaps in the understanding of the universe at the particle physics level. A critical task during the first two- year data taking will be to calibrate the detector and improve its operation while beginning to conduct initial physics studies.I propose to use the early ATLAS data to measure the efficiency and background rate of the muon trigger, and employ di-muon final states to begin a physics analysis program in the areas of quantum chromodynamics, B physics, and physics beyond the standard model. This will be done through measurement of the polarization of prompt J/psi mesons, study of semi-muonic penguin B decays, and a search for heavy new particles decaying to a pair of muons.
