Title: Improved Measurement of B(D{sup +}{yields}{mu}{sup +}{nu}) and the Pseudoscalar Decay Constant f{sub D{sup +}}

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.
