Measurement of the absolute branching fractions for D-s(-) --> l(-) (nu)over-bar(l) and extraction of the decay constant f(Ds)
The absolute branching fractions for the decays Ds--->ℓ-[nu] ℓ (ℓ=e, mu, or tau) are measured using a data sample corresponding to an integrated luminosity of 521 fb-1 collected at center-of-mass energies near 10.58 GeV with the BABAR detector at the PEP-II e+e- collider at SLAC. The number of D...
