Beauty and charm physics at CDF Run II

Abstract

Using the data samples collected with the CDF Run II detector during the year 2002 and early 2003, new measurements of the production cross-sections and the masses, lifetimes and branching fractions of beauty and charm hadrons are presented. New measurements of the Λ _b mass, lifetime, and branching fractions have greatly improved the current knowledge of bottom baryon properties and decay dynamics. The large charm signals made available by the silicon vertex track trigger have enabled the establishment of key measurements using rare charm decays that are sensitive to new physics beyond the Standard Model. The decay signals B _s → D _s π and the two body charmless decays of B⁰ and B _s have been established. These decay channels are important milestones towards the measurement of B _s mixing and direct CP violation in the B system.
