    abstract = "A measurement of B meson lifetimes is presented using data collected from 1991 to 1993 by the DELPHI detector at the LEP collider. Samples of events with a D meson and a lepton in the same jet are selected where {Mathematical expression} and D*ℓ+ events originate mainly from the semileptonic decays of B+ and B0 mesons, respectively. From the reconstructed B decay length and the estimated B momentum, taking into account the dilution due to B decays into {Mathematical expression}, the following B meson lifetimes and lifetime ratio are measured: {Mathematical expression} and an average lifetime of B+ and B0 mesons is obtained: {Mathematical expression} © 1995 Springer-Verlag."
