B-lifetime measurements at the tevatron
- Fermi National Accelerator Lab., Batavia, IL (United States)
During the run period from May 1992 to begin of June 1993 the Collider Detector at Fermilab (CDF) has recorded {approx} 21.4 pb{sup {minus}1} of p{anti p} collider data at {radical}s = 1.8 TeV. For this run the detector had been upgraded which significantly enhanced its b-physics capabilities. The upgrades include a high precision Silicon VerteX detector (SVX) which enables CDF to reconstruct the decay vertex and decay length of b-hadrons. In this article the author reports on several measurements of the lifetime of b-flavored hadrons. The determination of the average b-lifetime using inclusive J/{psi}`s, the measurement of the B{sup {+-}} and B{sup 0} lifetimes by reconstructing exclusive final states including a J/{psi} or {psi}(2S) and a measurement of the B{sub s}{sup 0} meson lifetime exploiting the decay: B{sub s} {yields} l{nu}D{sub s}{sup +} {yields} l{nu}{phi}{pi}{sup +} {yields} l{nu}K{sup +}K{sup {minus}}{pi}{sup +}.
