dc.description.abstractWe extract a relatively precise value for the decay constant of the D+ meson by measuring B(D+->mu(+)nu)=(4.40 +/- 0.66(-0.12)(+0.09))x10(-4) using 281 pb(-1) of data taken on the psi(3770) resonance with the CLEO-c detector. We find f(D)(+)=(222.6 +/- 16.7(-3.4)(+2.8)) MeV, and compare with current theoretical calculations. We also set a 90% confidence upper limit on B(D+-> e(+)nu)< 2.4x10(-5) which constrains new physics models.
