Evidence for tt̄γ production and measurement of σtt̄γ/σtt̄
Using data corresponding to 6.0fb-1 of pp̄ collisions at √s=1.96TeV collected by the CDF II detector, we present a cross section measurement of top-quark pair production with an additional radiated photon in the central region with 10 GeV or more of transverse energy tt̄γ. The events are selected by...
