Title: Searching for Peculiar Top-like events at CDF and ATLAS
Host: Mike Mulhearn
Room: 416
The Tevatron and LHC have produced large samples of top-quark events. An impressively broad program of analysis has tested nearly every aspect of these events, to verify the Standard Model nature of the top quark, yielding no surprises other than the top-quark foward-backward asymmetry. But there remain important unexplored opportunities. Inspired by models designed to explain Afb, I will discuss studies of unexplored experimental signatures inside WWbb+jet events, which mimic the top quark signature and may be hiding inside the top quark sample. I will present the first search for top+jet resonances, the first search to use boosted hadronic W bosons, new same-sign top quark limits, new heavy quark limits, and discuss ttbar+jet resonances, as well as the possibility that Higgs cascades could be hiding inside WWbb events.
