Measurement Of Radiative D Meson Decays At Cleo C PDF Download

"We are interested in measuring the exclusive semileptonic decays of the Ds to greater precision because it is the least extensively studied of the ground state charmed mesons, and greater knowledge of the Ds's decays may give information on related processes. We have studied semileptonic decay of the Ds meson using the full data set collected near the D*sDs peak production energy of 4170 MeV with the CLEO-c detector. We have made improved measurements of the branching fractions of Cabibbo favored semileptonic decays [formula would not render] and [formula would not render]. We have also made observations of the branching fractions of Cabibbo suppressed semileptonic decays [formula would not render] and [formula would not render]. These branching fractions are the most precisely measured to date"--Page vi.
