We have searched for exclusive $\ensuremath{\gamma}\ensuremath{\gamma}$ production in proton-antiproton collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$, using $532\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ of integrated luminosity taken by the run II Collider Detector at Fermilab. The event signature requires two electromagnetic showers, each with transverse energy ${E}_{T}>5\text{ …

This article presents a measurement of the top quark mass using the CDF II detector at Fermilab. Colliding beams of protons and antiprotons at Fermilab's Tevatron ($\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$) produce top/antitop pairs, which decay to ${W}^{+}{W}^{\ensuremath{-}}b\overline{b}$; events are selected where one $W$ …
