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

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

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

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.
