We report a preliminary result for D0-D0bar mixing and the doubly Cabibbo suppressed decay rate R_D based on an analysis of D0 -> K+ pi- decays from 57.1 inverse fb of data collected at or just below the Y(4S) resonance with the BaBar…
Using the 9 inverse femtobarn data sample collected with the CLEO II.V detector at the Cornell Electron Storage Ring, we have studied the resonant substructure of the Cabibbo suppressed decay D0 -> pi+ pi- pi0. We observe significant…
Recent CLEO results on neutral charm meson decays presented at the XXXVIth Rencontres de Moriond are discussed. We find no evidence of CP asymmetry in five different two-body decay modes of the D0 to pairs of light pseudo-scalar mesons. We…
We present a search for D0--anti-D0 mixing in the decays D0 --> K+ pi- pi+ pi- using 230.4 fb-1 of data collected with the BaBar detector at the PEP-II e+ e- collider at SLAC. Assuming CP conservation, we measure the time-integrated mixing…
We have observed four fully reconstructed B0 -> D*+D*- candidates in 5.8 million Upsilon(4S) -> BBbar decays recorded with the CLEO detector. The background is estimated to be 0.31 +- 0.10 events. The probability that the background could…
We analyze 230.4 fb-1 of data collected with the BaBar detector at the PEP-II e+ e- collider at SLAC to search for evidence of D0--anti-D0 mixing using regions of phase space in the decay D0 --> K+ pi- pi0. We measure the time-integrated…
We report the new measurement of D0 - D0bar mixing in decays to K+K- and pi+pi- final states that is based on the total Belle data sample of 976 /fb. The preliminary results are y_CP=(1.11 +- 0.22 +- 0.11)% and A_Gamma=(-0.03 +- 0.20 +-…
We exploit the quantum coherence between pair-produced D0 and D0bar in psi(3770) decays to study charm mixing, which is characterized by the parameters x and y, and to make a first determination of the relative strong phase \delta between…
We present recent results in the charm sector from the CLEO Collaboration. The data used were collected by the CLEO II and III detectors at the Cornell Electron Storage Ring (CESR). Measurements of form factors and branching fractions in…
We present preliminary results of several analyses searching for the effects of CP violation and mixing in the decay of $D^0$ mesons. We find no evidence of CP asymmetry in five different two-body decay modes of the $D^0$ to pairs of light…
We report a direct measurement of $D^0-overline{D}^0$ mixing parameters through a time-dependent amplitude analysis of the Dalitz plots of $D^0 \rightarrow K_S^0 \pi^+ \pi^-$ and, for the first time, $D^0 \rightarrow K_S^0 K^+ K^-$ decays.…
We report an improved measurement of D0-D0bar mixing and a search for CP violation in D0 decays to CP-even final states K+K- and pi+pi-. The measurement is based on the final Belle data sample of 976/fb. The results are y_CP=(1.11 +- 0.22…
We report on a direct measurement of the mixing parameter y=(3.42+-1.39+-0.74)% in the D0-D0bar system by measuring the lifetime difference between the CP mixed final state K^+pi^- and the CP even state K^+K^-. We also present a study of…
The CLEO-c detector at CESR has begun to collect large data sets of $e^+e^- \to c\bar{c}$ events in the center-of-mass energy range $\sqrt{s}=3 - 5 $GeV that will greatly enhance the size of the world's data sets of events produced at charm…
The decays Upsilon(4S) -> BB, followed by B -> D* pi and D* -> D pi, permit reconstruction of all kinematic quantities that describe the sequence without reconstruction of the D, with reasonably low backgrounds. Using an integrated e+e-…
We report on a measurement of D0-D0bar mixing and a search for CP violation in the D0->K+K-, pi+pi- and K+-pi-+ channels. We use D0's coming from D*+ decays, so that the flavour of the D0 at production is tagged by the charge of the pion…

Quantum correlations in $\psi(3770) \to D^0\bar{D}^0$ provide unique access to information about strong phase differences. Precision determination of the CKM phase $\gamma/\phi_3$ via $B \to D K$ decays depends upon constraints on charm…
