Available in PDF, EPUB and Kindle. Book excerpt: We report updated results in the search for B{sub s} flavor oscillations performed at CDF II. We analyze a dataset of approximately 355 pb{sup -1} from proton-antiproton collisions at a center-of-mass energy of 1.96 TeV collected in 2002-2004 with the CDF II detector at the Tevatron Collider. Samples of both fully reconstructed B{sub s} {yields} D{sub s}(3){pi}, and partially reconstructed, B{sub s} {yields} D{sub s}{ell}X, decays have been studied. A combination of opposite side tagging algorithms has been used to determine the flavor of the B{sub s} mesons at production time. Information about the oscillation frequency of the system, {Delta}m{sub s}, is obtained by performing an amplitude scan of the data, from which an exclusion limit {delta}m{sub s} {ge} 8.6ps{sup -1} ({at} 95% C.L.), with a measured sensitivity of 13.0 ps{sup -1} has been derived; Combination with previously available measurements increases the world exclusion limit from 14.5 ps{sup -1} to 16.6 ps{sup -1} ({at} 95% C.L.).
