Search for Stopped Gluinos in pp collisions at sqrt s = 7 TeV
arXiv:1011.5861 · doi:10.1103/PhysRevLett.106.011801
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 10^{32} cm^{-2} s^{-1}, an integrated luminosity of 10 inverse picobarns, 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 between the gluino and the neutralino greater than 100 GeV/c^2, and assuming a branching ratio for gluino to gluon+neutralino of 100%, gluinos of mass less than 370 GeV/c^2 are excluded for lifetimes from 10 microseconds to 1000 s.
