Search for stopped gluinos in pp collisions at vs=7TeV

Abstract: The results of the first search for long-lived gluinos produced in 7 TeV pp collisions at the CERN Large Hadron Collider are presented. The search looks for evidence of long-lived particles that stop in the CMS detector and decay in the quiescent periods between beam crossings. In a dataset with a peak instantaneous luminosity of 1×1032??cm?2?s?1, an integrated luminosity of 10??pb?1, and a search interval corresponding to 62 hours of LHC operation, no significant excess above background was observed. Limits at the 95% confidence level on gluino pair production over 13 orders of magnitude of gluino lifetime are set. For a mass difference m?g?m??01>100??GeV/c2, and ssuming BR(?g?g??01)=100%, m?g<370??GeV/c2 are excluded for lifetimes from 10???s to 1000 s
