OSTI ID:940085
Using data samples in excess of 1 fb{sup -1} collected by the CDF II detector we present several world's best measurements of B hadron lifetimes. They include B{sub s} meson lifetime in a flavor-specific decay mode, combining fully and partially reconstructed hadronic decays, B{sub c}{sup +} meson lifetimes in semileptonic B{sub c}{sup +} -> J/psi l+ X, l+ = mu+,e+ decays and Lambda{sub b} baryon lifetime in Lambda{sub c}{sup +} pi- fully-reconstructed decays. In addition, we introduce a Monte Carlo independent technique for measuring B hadron lifetimes in data samples biased by displaced vertex triggers.
