Using 281 pb^-1 of data collected with the CLEO-c detector, we present new measurements of Cabibbo-suppressed decays of D0 and D+ mesons to eta and eta' final states. We make first observations of D0-->eta'pi0, eta eta, eta eta', and eta…

The symmetric $e^+e^-$ collider CESR is undergoing a series of upgrades allowing for luminosities in excess of $2\times 10^{33}$cm$^{-2}$s$^{-1}$. The most important goals of the upgrade are precision measurement of standard model…

Using a 13.7 fb-1 data sample collected with the CLEO II and II.V detectors, we report new branching fraction measurements for two Cabibbo-suppressed decay modes of the D+ meson: BR(D+ -> pi+ pi0) = (1.31 +/- 0.17 +/- 0.09 +/- 0.09) x…

We measure the $D^0 - {\bar{D}}^0$ mixing parameters using a time-dependent amplitude analysis of the decay $D^0\to\pi^+\pi^-\pi^0$. The data were recorded with the BABAR detector at center-of-mass energies at and near the $\Upsilon(4S)$…

Future asymmetric e+e- --> Upsilon(4S) B factories are being constructed to search for CP violation in B0 decays. It is hoped that a CP asymmetry may be observed in B0-B0bar mixing in analogy with that found in neutral kaons. In this mixing…
