Abstract

Using data samples in excess of 1 fb^-1 collected by the CDF II detector we present several world's best measurements of B hadron lifetimes. They include B_s meson lifetime in a flavor-specific decay mode, combining fully and partially reconstructed hadronic decays, B_c⁺ meson lifetimes in semileptonic B_c⁺ -> J/psi l+ X, l+=mu+,e+ decays and Lambda_b baryon lifetime in Lambda_c⁺ 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.
