1  Measured mean life using fully reconstructed decays (J/ψK()).
2  Measured using B D0π with D0 Kπ+ events that were selected using a silicon vertex trigger.
3  Measurement performed using a combined fit of CP-violation, mixing and lifetimes.
4  Measurement performed using an inclusive reconstruction and B flavor identification technique.
5  Measured mean life using fully reconstructed decays.
6  Events are selected in which one B meson is fully reconstructed while the second B meson is reconstructed inclusively.
7  Data analyzed using D / D X event vertices.
8  Data analyzed using charge of secondary vertex.
9  ABREU 1995Q assumes B( B0 D+ν) = 3.2 ±1.7%.
10  Data analyzed using vertex-charge technique to tag B charge.
11  Combined result of D/D X analysis and fully reconstructed B analysis.
12  Combined ABREU 1995Q and ADAM 1995 result.
