| dc.description.abstract | Many models of new physics include the possibility of a new massive long-lived particle, the existence of which could explain discrepancies between cosmological theories and observations of 6 Li and 7 Li in the early universe. We search for particles stopping in the CMS detector after production in 7 TeV collisions at the LHC. We look for decays using a specially modified jet trigger, in time periods in which no collisions occur in CMS. In a search interval corresponding to 62 hours of LHC operation, consisting of 10.2 pb-1 of integrated luminosity with a peak instantaneous luminosity of 1032 cm-2 s-1 , we observe no significant excess over background. We set a 95% C.L. limit on production of Split-Supersymmetry gluinos over 14 orders of magnitude of gluino lifetime. | en_US |
