Search for Long-Lived Massive Charged Particles in 1.96 TeV pp-bar Collisions

We performed a signature-based search for long-lived charged massive particles produced in 1.0  fb[superscript -1] of pp̅ collisions at √s=1.96  TeV, collected with the CDF II detector using a high transverse-momentum (pT) muon trigger. The search used time of flight to isolate slowly moving, high-...

Description
Summary:We performed a signature-based search for long-lived charged massive particles produced in 1.0  fb[superscript -1] of pp̅ collisions at √s=1.96  TeV, collected with the CDF II detector using a high transverse-momentum (pT) muon trigger. The search used time of flight to isolate slowly moving, high-p[subscript T] particles. One event passed our selection cuts with an expected background of 1.9±0.2 events. We set an upper bound on the production cross section and, interpreting this result within the context of a stable scalar top-quark model, set a lower limit on the particle mass of 249  GeV/c[superscript 2] at 95% C.L.
