1ST MEASUREMENT OF GAMMA(D(S)(+)-]MU+NU)/GAMMA(D(S)(+)-]PHI-PI+)
We present a measurement of GAMMA(D(s)+ --> mu+nu)/GAMMA(D(s)+ --> phipi+) = 0.245 +/- 0.052 +/- 0.074. Using this ratio and B(D(s)+ --> phipi+)=(3.7 +/- 0.9)% we extract f(Ds)=344 +/- 37 +/- 52 +/-42 MeV, where the last error is due to the uncertainty in the D(s)+ --> phipi+ absolute br...
