Description
At first order all b-hadrons have equal lifetimes given by the lifetime of
b-quark. The effects of spectator quark in the hadron then introduces
corrections which yields to differences in the b-hadron lifetimes. The
corrections can be predicted rather precisely and therefore precise
measurements can test our understanding of spectator effects. We report
measurements of lifetimes of B+, B0,Bs and Lambda_b performed at CDF using
significantly larger data samples than previously available. Samples
include both final states with J/psi in the final state as well as
semileptonic and fully hadronic final states collected by impact-parameter
based triggers.
