We report the preliminary results of a search for long-lived particles produced in 7 TeV pp collisions from CERN’s Large Hadron Collider. We have looked for long-lived particles which have stopped in the CMS detector. We search for the subsequent decay of these particles during time intervals where there were no pp collisions. In particular, we search for decays during gaps between crossings...

We report the preliminary results of a search for HSCP produced in 7 TeV pp collisions from CERN’s Large Hadron Collider. A signature-based search for heavy stable charged particles using a high transverse-momentum muon trigger was performed. The search uses time-of-flight and ionization energy loss to isolate slowly moving, heavy, high transverse momentum particles. This result is interpreted...

MUSiC is a tool for model independent searches in the data recorded by the CMS experiment. Such an analysis can help to understand the detector and later to discover new physics by systematically scanning the data for deviations from the standard model expectations. Sensitivity to a wide range of models for new physics is achieved by minimizing the theoretical bias. Kinematic distributions,...

If a model such as split-SUSY is realized in nature, R-hadrons, which contain a long-lived gluino or squark,
can be produced and detected by the ATLAS experiments at the CERN Large Hadron Collider.
These particles will traverse the detector and may lose enough of their energy through ionization to become
captured and stop in the densest materials. Such "stopped" particles would decay at...

At the LHC, many new physics signatures feature the pair-production of massive particles with subsequent direct or cascading decays to weakly-interacting particles, such as SUSY scenarios with conserved R-parity or H->W(lnu)W(lnu). We present a novel set of dimension-less variables that can be used in establishing the discovery of processes of this type in conjunction with a set of variables...
