Abstract

We present a measurement of GAMMA(D(s)+ --> mu+nu)/GAMMA(D(s)+ --> phi pi+) = 0.245 +/- 0.052 +/- 0.074. Using this ratio and B(D(s)+ --> phi pi+)=(3.7 +/- 0.9)% we extract f(Ds)=344 +/- 37 +/- 52 +/-42 MeV, wher e the last error is due to the uncertainty in the D(s)+ --> phipi+ abs olute branching ratio. This result is larger than most theoretical pre dictions.
