Precision Measurement of B(D+ -> mu+ nu) and the Pseudoscalar Decay Constant fD+

Autor: CLEO Collaboration, Eisenstein, B. I.

Publikováno v: Phys.Rev.D78:052003,2008

We measure the branching ratio of the purely leptonic decay of the D+ meson with unprecedented precision as B(D+ -> mu+ nu) = (3.82 +/- 0.32 +/- 0.09)x10^(-4), using 818/pb of data taken on the psi(3770) resonance with the CLEO-c detector at the CESR

Hadronic Branching Fractions of D^0 and D^+, and sigma(e^+e^- --> D bar{D} at E_{cm} = 3.77 GeV

Autor: Eisenstein, B. I., Collaboration, CLEO

Using nearly 60 pb-1 of data collected with the CLEO-c detector at the psi_prime resonance, we measure absolute branching fractions for three D0 and two D+ Cabibbo-allowed hadronic decay modes, and the cross section for e+e- to D Dbar at Ecm = 3.77 G

Measurement of the Charge Asymmetry in $B\to K^* (892)^{\pm}\pi^{\mp}$

Autor: Eisenstein, B. I.

We report on a search for a CP-violating asymmetry in the charmless hadronic decay B -> K*(892)+- pi-+, using 9.12 fb^-1 of integrated luminosity produced at \sqrt{s}=10.58 GeV and collected with the CLEO detector. We find A_{CP}(B -> K*(892)+- pi-+)

Report

Experimental Investigation of the Two-Photon Widths of the $\chi_{c0}$ and the $\chi_{c2}$ Mesons

Autor: Eisenstein, B. I., Collaboration, CLEO

Publikováno v: Phys.Rev.Lett.87:061801,2001

Using 12.7 $fb^{-1}$ of data collected with the CLEO detector at CESR, we observed two-photon production of the $c \bar c$ states $\chi_{c0}$ and $\chi_{c2}$ in their decay to $\pi^+ \pi^- \pi^+ \pi^-$. We measured $\Gamma_{\gamma\gamma}(\chi_{c}) \t
