Abstract
Using a data sample of 1475000 Z --> q (q) over bar(gamma) events coll ected during 1993 with the L3 detector at LEP, we have studied the pur ely leptonic decays of heavy flavour mesons, D-s(-) --> tau(-)(v) over bar(tau) and B- --> tau(-)(v) over bar(tau). A signal is observed in the invariant mass distribution M(gamma D-s(-)) corresponding to the d ecay sequence D-s(-) --> gamma D-s(-), D-s(-) --> tau(-)(v) over bar( tau), tau(-)(v) over bar(tau), tau(-) --> l(-)(v) over bar(l)v(tau). T he branching fraction for D-s(-) tau(-) (v) over bar(tau) decays is me asured to be B(D-s(-) --> tau(-)(v) over bar(tau)) = 0.074 +/- 0.028(s tat) +/- 0.016(syst) +/- 0.018(norm). No signal of B- --> tau-(v) over bar(tau) decays is observed in the data, corresponding to an upper li mit on the branching fraction B(B- --> tau(-)(v) over bar(tau)) < 5.7 x 10(-4) at 90% CL.
