摘要：

We performed a signature-based search for long-lived charged massive particles produced in 1.0 fb(-1) of p (p) over bar collisions at root s 1.96 TeV, collected with the CDF II detector using a high transverse-momentum (p(T)) muon trigger. The search used time of flight to isolate slowly moving, high-p(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(2) at 95% C. L.
