Search for Heavy Stable Charged Particles at CMS Using Tracker dE/dx Measurement

This dissertation starts with an overview of the physics of heavy stablecharged particles, which arise in various models beyond the standard modellike supersymmetry and universal extra dimensions. Then it describes thecurrent experimental status on searching for these particles. The main content of this dissertation is discussing the physics potential of the compactmuon solenoid (CMS) detector at the large hadron collider (LHC) in detecting such high-mass particles, primarily using dE/dx information from thesilicon strip tracker system of CMS, based on Monte-Carlo simulation data.Cosmic data from the Tracker Integration Facility is also used to better understand the performance of tracker dE/dx measurements.
