B0 and B+ lifetime measurements at LEP

Using either D lepton correlations or secondary vertex charge measurements, b-quark jets are separated into B + and B 0 enriched samples. Preliminary results on lifetimes of these separated b-samples are presented, exploiting the good vertex resolution of the DELPHI and ALEPH silicon microvertex detectors. Within errors, the B + and B 0 lifetimes appear to be equal.
