We consider the possibility that D^0 - anti-D^0 mixing undergoes resonant enhancement. Various scenarios are explored, including the potential effects of nearby pseudoscalar or scalar quark-antiquark (Q - anti-Q) resonances as well as of hybrid quark-antiquark-gluon Q - anti-Q G states. Assuming reasonable values for the resonance parameters we find relatively sizeable contributions from individual resonances to both \Delta m_D and \Delta \Gamma_D. We derive a variant of the GIM cancellation mechanism for the resonance amplitudes and show that broken SU(3) can allow for sizeable residual effects. Additional input from meson spectroscopy and lattice gauge simulations will be needed to improve the accuracy of these predictions.

    First calculation of dimension-11 and dimension-12 QCD condensate contributions to D-meson mixing gives xD = 1.27e-5, still below experiment.
