Abstract

We point out how, in certain models of new physics, the same combination of couplings occurs in the amplitudes for both D0-D̅ 0 mixing and the rare decays D0→ℓ+ℓ-. If the new physics dominates and is responsible for the observed mixing, then a very simple correlation exists between the magnitudes of each; in fact the rates for the decay D0→ℓ+ℓ- are completely fixed by the mixing. Observation of D0→ℓ+ℓ- in excess of the standard model prediction could identify new physics contributions to D0-D̅ 0 mixing.
