This paper emphasizes four topics that represent some of the year's highlights in heavy quark physics. First of all, a review is given of charm lifetime measurements and how they lead to better understanding of the mechanisms of charm decay. Secondly, the CLEO collaboration's new search for charm mixing is reported, which significantly extends the search for new physics in that sector. Thirdly, important updates in Bs mixing are summarized, which result in a new limit on ΔMs, and which further constrain the unitarity triangle. Finally, the first efforts to measure CP violation in the B system are discussed. Results are shown for the CDF and ALEPH measurements of sin 2β, as well as the CLEO branching fraction measurements of B→Kπ, ππ, which have implications for future measurements of α.

The LHCb Collaboration has recently reported the discovery of direct CP violation in combined [Formula: see text] and [Formula: see text] decay modes at the [Formula: see text] level. Assuming U-spin symmetry (i.e. [Formula: see text] interchange symmetry) for the strong-interaction parts of these two channels, we find that their corresponding direct CP-violating asymmetries are [Formula: see text] and [Formula: see text]. The CP-forbidden transition [Formula: see text] on the [Formula: see text] resonance is therefore expected to have a branching fraction of [Formula: see text] or smaller under U-spin symmetry, and it can be observed at a high-luminosity super-[Formula: see text]-charm factory if at least [Formula: see text] pairs of coherent [Formula: see text] and [Formula: see text] events are accumulated.
