Abstract

I discuss new results on absolute branching ratios of charm mesons into specific exclusive final states, Cabibbo suppressed decay rates, inclusive decays to ss mesons, limits on D0 → D̄0mixing, CP violation and T vio- lation. Preliminary results from CLEO-c now dominate the world average absolute branching fractions. For the most important normalization modes involving D0 and D+, the averages are B(D0 → K-π+) = (3.87 ± 0.06)%; and B(D+ →K-π+ π +) = (9.12 ± 0.19)%: For the D+ S CLEO-c measures B(D+ S→K-K+ π +) = (4.54 +0.44-0.42± 0.25)%. Using this rate, I derive an effective branching ratio Beff (D+ S → ø π +) = (3.49 ±0.39)%, that is appropriate for use in extracting other branching fractions that have often been measured relative to this mode. This number is compared with other determinations.
