Search for Long-Lived Massive Charged Particles in 1.96 TeV $\bar{p}p}$ Collisions

Abstract

We performed a signature-based search for long-lived charged massive particles (CHAMPs) produced in 1.0 ${\mathrm{fb}}^{-1}$ of $\bar{p}p$ collisions at $\sqrt{s}=1.96$ 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 $1.9\pm 0.2$ 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.
