Rare B Decays Mixing And Cp Violation At Tevatron PDF Download

Between 1992 to 1996, the CDF and D0 detectors each collected data samples exceeding 100 pb−1 of p{bar p} collisions at √s = 1.8 TeV at the Fermilab Tevatron. These data sets led to a large number of precision measurements of the properties of B hadrons including lifetimes, masses, neutral B meson flavor oscillations, and relative branching fractions, and to the discovery of the B0 meson. Perhaps the most exciting result was the first look at the CP violation parameter sin ({vert_bar}2[beta]){vert_bar} using the world's largest sample of fully reconstructed B°/{bar B}° → J/[psi]K{sub s}° decays. A summary of this result is presented here. In the year 2000, the Tevatron will recommence p{bar p} collisions with an over order of magnitude expected increased in integrated luminosity (1 fb−1 per year). The CDF and D0 detectors will have undergone substantial upgrades, particularly in the tracking detectors and the triggers. With these enhancements, the Tevatron B physics program includes precision measurements of sin(2[beta]) and B{sub s}° flavor oscillations, as well as studies of rare B decays that are sensitive to new physics. The studies of B{sub s}° mesons will be particularly interesting as this physics will be unique to the Tevatron during the first half of the next decade.
