Book Description
The authors report a measurement of the B{sub s}° lifetime in the semileptonic decay channel B{sub s}° → D{sub s}−??X (and its charge conjugate), using approximately 0.4 fb−1 of data collected with the D0 detector during 2002-2004. They have reconstructed 5176 D{sub s}−?+ signal events, where the D{sub s}− is identified via the decay D{sub s}° →??−, followed by? → K+K−. Using these events, they have measured the B{sub s}° lifetime to be?(B{sub s}°) = 1.398 ± 0.044 (stat){sub -0.025}{sup +0.028}(syst) ps. This is the most precise measurement of the B{sub s}° lifetime to date.

Book Description
This thesis describes a measurement of the B$0\atop{d}$ lifetime in the decay to (J/?K$0\atop{S}$), using 114 pb-1 of data collected by the D0 experiment at the Tevatron from October 15, 2002, to June 10, 2003. The measurement is motivated by the tests of the Standard Model that it makes possible. These include tests of Heavy Quark Effective Theory predicting B-meson lifetimes, and of the complex phase in the CKM-matrix as the source of CP-violation in B$0\atop{d}$ decays to (J/?K$0\atop{S}$).

Book Description
A high statistics measurement of the D{sub s}+ lifetime from the Fermilab fixed-target FOCUS photoproduction experiment is presented. They describe the analysis of the two decay modes, D{sub s}+ → ?(1020)?+ and D{sub s}+ → {bar K}*(892)°K+, used for the measurement. The measured lifetime is 507.4 ± 5.5(stat.) ± 5.1(syst.) is using 8961 ± 105 D{sub s}+ → ?(1020)?+ and 4680 ± 90 D{sub s}+ → {bar K}*(892)° K+ decays. This is a significant improvement over the present world average.

Book Description
This thesis describes a measurement of the lifetime of the [Lambda]$0\atop{b}$ baryon, performed using data from proton-antiproton collisions at a centre of mass energy of 1.96 TeV. The decay [Lambda]$0\atop{b}$ → [Lambda]$+\atop{c}$[mu]-$\bar{v}$[mu]X was reconstructed in approximately 1.3 fb[mu]-1 of data recorded by the D0 detector in 2002-2006 during Run II of the Fermilab Tevatron collider. A signal of 4437 ± 329 [Lambda]$+\atop{c}$[mu]- pairs was obtained, and the [Lambda]$0\atop{b}$ lifetime was measured using a binned X2 fit, which gives a value [tau]([Lambda]$0\atop{b}$) = 1.290$+0.091\atop{-1.110}$(stat)$+0.085\atop{-0.091}$(syst) ps. This result is consistent with the world average and is one of the most precise measurements of this quantity.
