Search for Stopped Gluinos in pp Collisions at root s=7 TeV
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 p...

| description | 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 [1 x 10 superscript 32] cm-2 s-1 [cm superscript -2 s superscript -1] , an integrated luminosity of 10 pb-1 [pb superscript -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 mg˜-mχ˜10>100 GeV/c2 [m subscript _ g minus m subscript -0 over X subscript 1, greater than 100 GeV over c superscript 2], and assuming BR(g˜→gχ˜10)=100% [BR (g → g X -0 subscript 1 = 100%], mg˜<370 GeV/c2 [m subscript g less than 370 GeV over c superscript 2]are excluded for lifetimes from 10 μs [mu s] to 1000 s |
