CP violation and CKM measurements in Bottom and Charm decays at CDF

We present preliminary measurements of branching ratios and CP asymmetries in 5 charmless decay modes of the B mesons and precise measurement of direct CP asymmetry in Cabibbo-suppressed charm decays. We used 180pb−1 of the hadronic-b data stream of CDF's Tevatron Run2. The decay mode Bs→ϕϕ has been observed for the first time, with a branching fraction of (1.4±0.6±0.2±0.5)×10−5. We also present the first measurement of the branching fraction B(Bs→K+K−)=(3.56±0.57±0.50±0.43)×10−5.
