Lifetime measurements for B0 and B+ are presented using semileptonic decays of B mesons from 360 pb-1 of data collected by CDF's lepton plus displaced track tri

The B[sup 0] lifetime has been measured with a sample of 23 million B[bar B] pairs collected by the BABAR detector at the PEP-II e[sup+]e[sup -] storage ring du

The lifetimes of the B− and {bar B}° mesons are measured using the partially reconstructed semileptonic decays in the CDF experiment.

We present here the first measurement of the B° lifetime using partial reconstruction in B° → D*−? decay. A sample of approximately 5500 B° → D*−?+ e
