Charm Mixing and Rare Decays
Abstract
There has been significant recent experimental activity on the related topics of charm mixing and rare (flavor changing neutral current) decay. For mixing, several new results from direct (wrong sign) searches and first results from lifetime difference (Delta Gamma) searches have been reported. Limits for rmix of approximately 5 x 10-4 (or better) are possible from work in progress. For rare decays, sensitivities to branching ratios are now at the level of a few x 10-6.
