Analysis Of Calorimeter/itc Cosmic Ray Data From The Atlas Detector, And Preparation For Supersymmetry Searches

Abstract

The Large Hadron Collider is the largest most ambitious experiment in high energy physics history. It involves the greatest number of scientists from around the world. The first collisions will start being produced in late 2009 and we expect that the information collected will help us understand the physics behind the standard model such as higgs physics and the supersymmetric theories. The Department of Physics at University of Texas at Arlington, and more specifically the high energy physics group is actively involved with the design, construction and commissioning process of the ATLAS Tile Calorimeter. The group is also participating in the ATLAS computational network, or Grid, with the installation of a Tier2 computing center at UTA campus. This work presents some of the commissioning tasks performed in the summers of 2006 and 2007, and also presents an analysis on the cosmic rays detection performance of the Intermediate Tile calorimeter cells. Finally, we present a study on MonteCarlo simulations for the dilepton invariant mass in supersymetric Msugra events
