Search for a Heavy Toplike Quark in pp̅ Collisions at √s=1.96 TeV
We present the results of a search for pair production of a heavy toplike (t′) quark decaying to Wq final states using data corresponding to an integrated luminosity of 5.6 fb[superscript -1] collected by the CDF II detector in pp̅ collisions at √s=1.96 TeV. We perform parallel searches for t′→Wb...

| description | We present the results of a search for pair production of a heavy toplike (t′) quark decaying to Wq final states using data corresponding to an integrated luminosity of 5.6 fb[superscript -1] collected by the CDF II detector in pp̅ collisions at √s=1.96 TeV. We perform parallel searches for t′→Wb and t′→Wq (where q is a generic down-type quark) in events containing a lepton and four or more jets. By performing a fit to the two-dimensional distribution of total transverse energy versus reconstructed t′ quark mass, we set upper limits on the t′t̅ ′ production cross section and exclude a standard model fourth-generation t′ quark decaying to Wb (Wq) with mass below 358 (340) GeV/c[superscript 2] at 95% C.L. |
