Measurement of branching ratio and Bs0 lifetime in the decay Bs0 -> J/psi f0(980) at CDF
CDF Collaboration, T. Aaltonen, B. Alvarez Gonzalez +512
We present a study of Bs0 decays to the CP-odd final state J/psi f0(980) with J/psi -> mu+ mu- and f0(980) -> pi+ pi-. Using ppbar collision data with an integrated luminosity of 3…
Improved determination of the sample composition of dimuon events produced in {\boldmath } collisions at {\boldmath } TeV
CDF Collaboration
We use a new method to estimate with 5% accuracy the contribution of pion and kaon in-flight-decays to the dimuon data set acquired with the CDF detector. Based on this improved es…
Search for the Rare Radiative Decay: in \ppbar\ Collisions at TeV
CDF collaboration, T. Aaltonen
We present a search for the rare radiative decay \wpigamma\ using data corresponding to an integrated luminosity of 4.3 \invfb\ of proton-antiproton collisions at a center of mass…
Observation of B0_s -> J/psi K*(892)0 and B0_s -> J/psi K0_S Decays
CDF Collaboration, T. Aaltonen
We report the first observation of two Cabibbo-suppressed decay modes of the B0_s meson. Using a sample of p-pbar collisions at sqrt{s}=1.96 TeV corresponding to 5.9 fb-1 of integr…
Evidence for D0-D0bar mixing using the CDF II Detector
CDF Collaboration, T. Aaltonen
We measure the time dependence of the ratio of decay rates for the rare decay D0->K+pi- to the Cabibbo-favored decay D0->K-pi+. We use a signal of 12.7 x10^3 D0->K+pi decays with p…
