摘要：

We describe plans for a search for long-lived particles which will become stopped by the CMS detector We will look for the subsequent decay of these particles during time intervals where there are no pp collisions in CMS during gaps between crossings in the LHC beam structure, and during inter-fill periods between the beam being dumped and re-injection. Such long living particles decays will be recorded with dedicated calorimeter triggers For models predicting these particles, such as split-susy gluinos, the large cross-section combined with good stopping power of CMS, yields a significant number of triggerable decays If LHC instantaneous luminosity approaches 10(32)cm(-2)s(-1) in 2009-10, 5 sigma significance can be established in a matter of days, since these decays occur on top of a negligible background Due to limited size. this paper concentrates on main Idea and expected results More details are available in https://twiki cern ch/twiki/bin/view/CMS/PhysicsResults
