Heavy Flavor Results from DØ

Presented are summaries of four heavy flavour analyses by the DØ Collaboration between August 2011 and June 2012. Using up to 10.4fb−1 of collisions at accumulated by the DØ detector at the Fermilab Tevatron collider, we find evidence for the two-body decay and measure the branching fraction of these decays relative to as . The lifetime is measured using the fully reconstructed decay , along with the lifetime of the topologically similar decay channel . The analyses yields results of ps, ps, and ps. A narrow mass state is observed that decays into ϒ(1S)+γ with an invariant mass of 10.551±0.014(stat.)±0.017(syst.)GeV/c2. Finally, the semileptonic charge asymmetry is measured to be using the decay channel .
