TL;DR: In this article, the decay constant of the D{sup +} meson was derived by measuring B(D{sup+}yields}{mu}{sup +}{nu}) = 4.40{+-}0.66{sub -0.12} 0.4x10{sup -5} which constrains new physics models.
Abstract: We extract a relatively precise value for the decay constant of the D{sup +} meson by measuring B(D{sup +}{yields}{mu}{sup +}{nu})=(4.40{+-}0.66{sub -0.12}{sup +0.09})x10{sup -4} using 281 pb{sup -1} of data taken on the {psi}(3770) resonance with the CLEO-c detector. We find f{sub D{sup +}}=(222.6{+-}16.7{sub -3.4}{sup +2.8}) MeV, and compare with current theoretical calculations. We also set a 90% confidence upper limit on B(D{sup +}{yields}e{sup +}{nu})<2.4x10{sup -5} which constrains new physics models.

TL;DR: In this paper, the authors used data collected by the CLEO III detector at the Cornell Electron Storage Ring to measure the inclusive yields of D(s) mesons as B(Y(5S) --> D(S)X) = (44-7 +/- 4.2 +/- 9.9)% at the 4S energy, and B(y(4S) and y(sX) were (18.1 +/- 0.5 +/- 2.8)%.
Abstract: We use data collected by the CLEO III detector at the Cornell Electron Storage Ring to measure the inclusive yields of D(s) mesons as B(Y(5S) --> D(s)X) = (44-7 +/- 4.2 +/- 9.9)% and B(Y(4S) --> D(s)X) = (18.1 +/- 0.5 +/- 2.8)%. From these measurements, we make a model dependent estimate of the ratio of B(s)*B(s)* to the total bb quark pair production of (16.0 +/- 2.6 +/- 5.8)% at the Y(5S) energy.

TL;DR: In this paper, the authors search for lepton number-violating decays of D+ mesons to final states with dielectrons using 0.8 x 10(6) pairs collected with the CLEO-c detector at the psi(3770) resonance.
Abstract: Using 0.8 x 10(6) D+ D- pairs collected with the CLEO-c detector at the psi(3770) resonance, we have searched for flavor-changing neutral current and lepton-number-violating decays of D+ mesons to final states with dielectrons. We find no indication of either, obtaining 90% confidence level upper limits of B(D+ --> pi+ e+ e-) pi- e+ d+) K+ e+ e-) K- e+ e+) < 4.5 x 10(-6).

TL;DR: In this article, the main goal is the measurement of the angles γ and β from B decays involving D or charmonium mesons, as well as new approaches and high statistics projections.
Abstract: The main goal is the measurement of the angles γ and β from B decays involving D or charmonium mesons. The limitations and ways to overcome them will be discussed, as well as new approaches and high statistics projections.
