Measurement of time integrated asymmetry which with the best sensitivity up to date (down to 3x10-3) shows the absence of CP violation in D meson decays.
COBISS.SI-ID: 23678247
While the measurement does not represent a direct measurement of the mixing parameters, the leptonic decays of D0 mesons (D0 -> l+l-) proceed through a similar processes as the mixing and hence offer similar constraints on several New physics models as the measurements of mixing and CP violation. The measurement established so far the most restrictive upper limits on the branching fractions of leptonic decays.
