Presented are summaries of four heavy flavour analyses by the DØ Collaboration between August 2011 and June 2012. Using up to 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 with an invariant mass of . Finally, the semileptonic charge asymmetry is measured to be using the decay channel . [ABSTRACT FROM AUTHOR]
