Search for Heavy Stable Charged Particle with 100 pb 1 and 1 fb 1 at CMS experiment

The CMS detector can be used to search for Heavy Stable Charged Particles (HSCPs) which might signal physics beyond the Standard Model. Such particles can be distinguished from Standard Model particles by exploiting their unique signature: a low velocity, , associated with a high momentum of order a few hundred GeV/c. In this note four models predicting different types of HSCP are described and used as benchmarks for a proposed search strategy. Two techniques to measure of such particles using the Silicon Tracker and the Barrel Muon Drift Tube detectors are reviewed, and results based on full simulation of the CMS detector are presented. These include the expected performance and resolutions which could be obtained using the first data from CMS at the LHC. The measurement of using other sub-detectors —the Endcap Muon Cathode Strip Chambers and the Electromagnetic Calorimeter— is also investigated. The HSCP mass regions explored for integrated luminosities of 100 pb 1 and 1 fb 1 are shown.
