Heavy Flavour Physics at CDF

We present recent CDF measurements of mass, lifetime and CP violation properties of B hadrons. The analyzes presented in this paper use up to 2.8/fb of data. CDF has already accumulated close to 5/fb of data which promises significant improvements of these analyzes in the near future.Comment: 4 pages, 3 figures, presented at Lake Louise Winter Institute 200

Bs Decays at the Tevatron

We present measurements of the branching ratio and of the polarization amplitudes in charmless Bs to Phi Phi decays using data corresponding to 2.9/fb of integrated luminosity, collected by the CDF experiment at the Tevatron. The branching ratio in Bs to Phi Phi decays is measured relative to the normalization mode Bs to J/Psi Phi$ to be B(Bs to Phi Phi)/B(Bs to J/Psi Phi) = [1.78 +/- 0.14 (stat) +/- 0.20 (syst)] x 10^{-2}. Using the experimental value of B(Bs to J/Psi Phi) we determine the Bs to Phi Phi branching ratio B(Bs to Phi Phi) = 2.40 +/- 0.21(stat) +/- 0.27(syst) +/- 0.82 (BR)] x 10^{-5}. The polarization fractions are measured for the first time in this analysis and found to be: |A_0|^2 = 0.348 +/- 0.041 (stat) +/- 0.021 (syst) |A_parallel|^2 = 0.287 +/- 0.043 (stat) +/- 0.011 (syst) |A_perp|^2 = 0.365 +/- 0.044 (stat) +/- 0.027 (syst).Comment: Presented at Flavor Physics and CP Violation - FPCP 2010, May 25-29, 2010, Turin, Ital

Reconstruction of High Transverse Momentum Top Quarks at CMS

High mass resonances decaying into ttbar pairs appear in many extensions of the Standard Model. The top quarks from these decays have high transverse momenta and their decay products are highly collimated due to the boost into the lab frame. As a result the standard techniques for reconstructing ttbar events begin to fail. In this talk we discuss the prospects for detecting booted top quarks at CMS. A new top jet tagging algorithm is presented. This algorithm achieves an efficiency of 46% for boosted top jets and rejection of 98.5% for generic QCD jets with transverse momenta of 600 GeV/$c$.Comment: To be published in the proceedings of DPF-2009, Detroit, MI, July 2009, eConf C09072

Review of Heavy Flavor Physics at the Tevatron

The D0 and CDF detectors at the Fermilab Tevatron have each accumulated more that 9/fb of integrated luminosity. The corresponding large datasets enable the two experiments to perform unprecedented studies of heavy flavor hadron properties. We present recent D0 and CDF measurements, focusing on rare decays and CP violation in B-meson decays.Comment: 12 pages, 8 figure
