Searching for Stopped Gluinos at CMS
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-...

description | 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. |
