Abstract

We have studied the leptonic decay Ds+→τ+ντ, via the decay channel τ+→e+νeν̄τ, using a sample of tagged Ds+ decays collected near the Ds*±Ds peak production energy in e+e- collisions with the CLEO-c detector. We obtain B(Ds+→τ+ντ)=( _5.30±_0.47±_0.22)% and determine the decay constant fDs=(_252.5±_11.1± _5.2)MeV, where the first uncertainties are statistical and the second are systematic.
