Evidence for t(t)over-bar gamma production and measurement of sigma(t(t)over-bar gamma)/sigma(t(t)over-bar) uri icon

abstract

  • Using data corresponding to 6.0fb-1 of pp 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 tt. The events are selected by looking for a lepton ( or ), a photon (), significant transverse momentum imbalance (ET), large total transverse energy, and three or more jets, with at least one identified as containing a b quark (b). Using an event selection optimized for the tt candidate sample, we also measure the cross section of tt (tt). We measure the tt cross section (tt) to be 0.180.08pb, and the ratio of tt to tt to be 0.0240.009. We observe a probability of 0.0015 (3.0 standard deviations) of the background (non-tt events alone producing 30 events or more. 2011 American Physical Society.
