Measurements of B hadron lifetimes at CDF
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 Bs meson lifetime in a flavor-specific decay mode, combining fully and partially reconstructed hadronic decays, Bc+ meson lifetimes in semileptonic Bc+ -> J/psi l+ X, l+=mu+,e+ decays and Lambdab baryon lifetime in Lambdac+ 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.
