9. Run II Luminosity updated Feb 1st, 2007
Highest initial Lum store: 270e30
Best integrated Lum week: 45 pb-1
Best integrated Lum month (January): 165 pb-1
We have 27 months left before Oct’09
If we just run like this, we could get to 7 fb-1

10. Instantaneous Luminosity Growth
Average Peak Luminosity Projections (design)
We are here

11. CDF Detector Operations
2.5 fb-1 delivered
2.0 fb-1 to tape
653 pb-1 delivered in FY06, 82% to tape
~5% trigger deadtime, ~5% beam conditions, ~5% problems
Overall our detectors remain healthy and ok with high luminosity
Our trigger is under close watch and still undergoing improvements
CDF has recorded 2 fb-1 of data
A major milestone !

15. CDF I (1985) Italia, Giappone, USA
The most important discovery, the Top quark ( )

16. CDF/D0 measurement of Top mass
current status
projected precision

17. CDF measurement of Bs oscillations
Precision and significance of this measurement are dominated by the hadronic data sample collected by the SVT trigger

18. CDF observation of new heavy baryons b and *b

19. CDF B  h+ h– results
First observation of Bs0  K-p+, Lb0  pp-, Lb0  pK-
First measurement of ACP and BR(Bs0  K-p+)
Precision ACP(B0  K+p-) measurement
Updated BR(Bs0  K+K-) and BR(B0  p+p-) measurements

20. CDF: inclusive jet production
Data vs. QCD predictions
Results are based on over 1 fb-1 of CDF Run II data. Measurements are fully unfolded to the parton level. The data is compared to pQCD NLO calculations as determined using EKS.

22. CDF measurement of W mass

23. After CDF new W mass result…
where is the Higgs?
The probability for MH > GeV is now 19%
most probable value is 80 GeV
MH < C.L.
