We examine e+e- to Ds- Ds*+ or Ds-* Ds+ collisions at 4170 MeV using the CLEO-c detector in order to measure the decay constant f_Ds+. We use the Ds+ to ell+ nu channel, where the ell+ designates either a mu+ or a tau+. Analyzing both modes…

A measurement of $C\!P$-violating observables in $B^{\pm} \to D^{*} K^{\pm}$ and $B^{\pm} \to D^{*} \pi^{\pm}$ decays is made where the photon or neutral pion from the $D^{*} \to D\gamma$ or $D^{*} \to D\pi^{0}$ decay is not reconstructed.…

We point out that in decays of the type $B^- \to D^* K^-$, where the neutral $D^*$ meson is an admixture of $D^{*0}$ and $\bar{D}^{*0}$, there is an effective strong phase difference of $\pi$ between the cases that the $D^*$ is…

We present preliminary measurements of D to K^0_L pi and D to K^0_S pi branching fractions using 281 pb^{-1} of psi(3770) data at the CLEO-c experiment. We find that BF(D^0 to KS pi^0) is larger than BF(D^0 to KL pi^0), with an asymmetry of…

Using 580 pb$^{-1}$ of $e^+e^-$ annihilation data taken with the CLEO--c detector at $\psi(3770)$, the decay $D^0(\overline{D}^0)\to K^\pm\pi^\mp \pi^+\pi^-$ has been studied to make the highest precision measurement of $D^0$ mass,…

Amplitude analyses of four body $D$ decays are of significant interest for multiple reasons, including their potential contribution to CP violation studies in both $B$ and $D$ decays. The resonant substructure of a four body decay has many…
