Abstract
From data recorded by DELPHI between 1991 and 1994, which corresponds to 3.2 million hadronic Z(0) decays, a measurement of the <(B-d(0))ove r bar> meson lifetime, based on the inclusive reconstruction of 3520 /- 150 semileptonic decays of the type <(B-d(0))over bar> --> D+ l <( nu(l))over bar>, has been performed, The result is: tau(B-d(0)) = 1.53 2 +/- 0.041(stat.) +/- 0.040(syst.)ps. The contribution to the systema tic uncertainty which depends on external errors is +/-0.015.
