Search for New Physics in High Pt Z+X (Preblessing) (Alexander Paramonov) ========================================================================= - Search for new heavy quarks pair produced and decay into WZ or ZZ - Look for excess in the high Z-pt tail - Using high Pt electron and muon data samples of ~305 pb-1 - Sasha does not observe any Z(ee,mumu)+gamma event for high Pt Z (pt>120 GeV). - Beate wanted to check why the high-pt Zgamma event in her analysis did not appear in Sasha's Z+gamma plots at high Z pt - She will send the run/event number to him. - Showed the signal acceptance as function of Z Pt (page 28). - The sharp drop in the acceptance at Pt~300 GeV maybe due to low MC statistic, and also due to isolation cut since the two lepton from Z decay are very close to each other - Do not understand the drop in acceptance at Pt~120 GeV (left plot (ee channel ?)) - Not sure if this is statistic issue, will generate more MC events - Compute limit for both ee and mumu channel separately. Conveners asked Sasha if he can combine results from both channels.
