Bottom and charm masses and lifetimes at the Tevatron; and a pentaquark search
The Fermilab Tevatron, operating at {radical}s = 1.96 TeV, provides a rich environment for the study of the bottom and charmed hadrons and for searches of other bound states. Presented here are recent measurements of the masses of the following states using fully reconstructed events: B{sup +}, B{sup 0}, B{sub s}, {Lambda}{sub b}, and the neutral B**. Lifetimes from both CDF and D0 in exclusive decays for all of these modes are also presented (sans the B**). A search was conducted at CDF for the {Xi}{sup 2} and {Xi}{sup 0} pentaquark states in the decay {Xi}(1860) {yields} {Xi}{sup -} {pi}{sup {+-}} setting a limit on their production in p-{bar p} collisions relative to the number of {Xi}(1530) baryons seen.
