Sarah’s 2005 : WW Scattering WW scattering at high mass (M WW ~ 1-2TeV): Considered several possible signals against W+jets and ttbar backgrounds. Analysis: p T cuts (>320GeV) on each of the W’s E (>300GeV) and η (>2.5) cuts on tag jets + further environment cuts. Studied optimum way to define hadronic W (2 overlapping jets), compared k T and cone algorithms. Also joined in with ATLAS full simulation effort: in initial selection of events with lepton and E T miss, found 65 % fewer events than ATLFAST, effect of subsequent cuts was ~ as predicted. More issues to be investigated yet: how to implement our hadronic W finding in full simulation, how well are backgrounds (W+jets) modelled, how to convince someone to make millions of background events for us? TO BE CONTINUED… Simon Head (Manchester), Stathis Stefanadis (UCL) Fast simulation of ATLAS detector (ATLFAST): TO APPEAR IN A THESIS NEAR YOU SOON.
