Signal with $H0\rightarrow Z A0$
Process $gg\rightarrow h0\rightarrow H0 H0 \rightarrow Z A0 Z A0 \rightarrow l+ l- l+ l- bbbb$
Signal (BP1, only eta<2.5 for b's), xsec before Z decays 463fb (already rescaled to best NLO with 1121/388!!!)
- LHE events, 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), 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!!!)
- LHE events, Root events both Zs into l+l- (50k, xsec=1.33 fb)
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)

Signal (BP3, no pT, eta cuts on b's, pt>10, eta<2.5 and dR>0.4 for leptons)
