Mixing in the D 0 system may provide a sensitive probe for new physics beyond the Standard Model (SM) but has so far eluded experimental observation. The SM predictions are typically small (< 10 -3 ) for the mixing parameters x, y which, in the absence of charge-parity (CP) symmetry violation, measure the mass (x = Δ m/Γ) and lifetime (y = ΔΓ/2Γ) difference of the CP eigenstates in the D 0 system. The asymmetric B-factory experiments BABAR and Belle open up the opportunity of measuring x, y with unprecedented statistical precision and sample purities. Results from BABAR and Belle, and from CLEO are reviewed.
