Abstract
We report a measurement of the lifetime of the B0 meson based upon 29-GeV e+e− annihilation data taken with the Mark II detector at the SLAC storage ring PEP. The B0 mesons are tagged by their decays into D*−e+ν and D*−μ+ν, where the D*− is tagged by its decay into π−D¯ 0. We reconstruct the decay vertices of 15 B0-meson candidates and measure the B0 lifetime to be 1.20−0.360.14+0.52+0.16 psec.
