Abstract

The branching ratio for the leptonic decay of charged B mesons (B- → τ-ν̄τ) has been measured using selected leptonic τ- → ℓ-ντν̄ℓ and hadronic τ- → ντX decays in Z → bb̄ decays recorded by DELPHI at LEP1 in 1992-1995. The result, BR(B-→τ-ν̄τ) ≤ 1.1 × 10-3 at the 90% confidence level, is consistent with standard model expectations and puts a 47 constraint on the ratio tan β/MH±
