D-Meson Mixing in Broken SU(3)
Thomas A. Kaeding
Abstract
A fit of amplitudes to the experimental branching ratios to two mesons is used to construct a new estimate of neutral D mixing which includes SU(3) breaking. The result is dominated by the experimental uncertainties. This suggests that the charm sector may not be as sensitive to new physics as previously thought and that long-distance calculations may not be useful.
