Signal (BP1, only eta<2.5 for b's), xsec before Z decays 463fb (already rescaled to best NLO with 1121/388!!!)

   * [attachment:ZAZABP1_out.lhe.gz LHE events], [attachment:ZAZABP1.root Root events] both Zs into l+l- (50k, xsec=2.09 fb)

Backgrounds:

Hopeless because too low pt ? Discuss how to group b jets, give xsec of main bkgrd ZZbb (0.3 fb with loose cuts on b's)

Plots : delta R (also BP2), pT 3rd and 4th jets (also for BP2),   [attachment:ptb34_zaza_bp1_bp2.eps ptb34_zaza_bp1_bp2.eps]

Signal (BP2, only eta<2.5 for b's), xsec before Z decays 314fb (already rescaled to best NLO with 802/120!!!)

If additional cuts on b's (pt>15,eta<2.5 and dR>0.4), cross section is 157,7fb.

Backgrounds (two b-tags)

   * ZZbbbb  to come euhhhh... 40ab!
   * ZZbbjj  to come, not feasable with ME... BUT: ZZbbj is 30fb (pt>15,eta<2.5 and dR>0.4 on all jets), so ZZbbjj is probably negligible.

Plots: mH0's and mh0 (from Arnaud's thesis)
