Download or read book Time Dependent B° - Bar-B° Mixing at SLD. written by and published by . This book was released on 2001 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report several preliminary studies of the time dependence of B{sub s}°-{bar B}{sub s}° and B{sub d}°-{bar B}{sub d}° mixing using a sample of 400,000 hadronic Z decays collected by the SLD experiment at the SLC. The study of B{sub d}°-{bar B}{sub d}° mixing determines a value of [Delta]m{sub d} = 0.503 ± 0.028(stat) ± 0.020(sys)ps−1. In the study of B{sub s}°-{bar B}{sub s}° mixing, oscillation frequencies up to [Delta]m{sub s}

Available in PDF, EPUB and Kindle. Book excerpt: The time dependence of B[sub d][sup o]-[bar B][sub d][sup o] mixing has been observed in events containing high P[sub t] leptons using a highly inclusive vertexing method to determine the B decay length and boost. The initial state B hadron flavour is determined using the large forward-backward asymmetry provided by the highly polarized electron beams of SLC in combination with a jet charge technique. From a sample of 150,000 hadronic Z[sup o] decays observed in the SLD detector at the SLC between 1993 and 1995, the mass difference between the two B[sub d][sup o] mass eigenstates has been measured to be [Delta]m[sub d] = 0.486 [+-] 0.065(stat) [+-] 0.035(syst) ps[sup -1].

Download or read book Time Dependent B{sub S}°-{bar B}{sub S}° Mixing Using Inclusive and Semileptonic B Decays at SLD. written by and published by . This book was released on 1999 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: We set a preliminary 95% C.L. exclusion on the oscillation frequency of B{sub s}°-{bar B}{sub s}° mixing using a sample of 350,000 hadronic Z° decays collected by the SLD experiment at the SLC during the 1997-98 run. The analyses determine the b-hadron flavor at production by exploiting the large forward-backward asymmetry of polarized Z° 2!b{bar b} decays as well as information from the hemisphere opposite that of the reconstructed B decay. In one analysis, B decay vertices are reconstructed inclusively with a new topological technique, and separation between B{sub s}° and {bar B}{sub s}° decays exploits the B{sub s}° 2!D{sub s}− cascade charge structure. In the other analysis, semileptonic decays are selected and the B decay point is reconstructed by intersecting a lepton track with the trajectory of a topologically reconstructed D meson. The two analyses are combined with a third analysis described elsewhere to exclude the following values of the B{sub s}°-{bar B}{sub s}° mixing oscillation frequency: [Delta]m{sub s}

This book was released on 1998 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors set a preliminary 95% C.L. exclusion on the oscillation frequency of B{sub s}°-{anti B}{sub s}° mixing using a sample of 250,000 hadronic Z° decays collected by the SLD experiment at the SLC between January 1996 and March 1998.

The other analysis selects semileptonic decays reconstructed by intersecting a lepton with he trajectory of a topologically reconstructed D meson.

Available in PDF, EPUB and Kindle. Book excerpt: The time dependence of B[sub d] -[bar B][sub d] mixing has been measured in b[bar b] events containing one or more kaons at the SLD experiment at the Stanford Linear Accelerator Center. A simultaneous measurement of the ''right sign production fraction'' of kaons from B[sub d] decays has also been made.

From a sample of 400,000 Z[sup 0] events collected by the SLD experiment at SLC from 1996 to 1998, the kaon right sign production fraction has been measured to be 0.797[+-] 0.022 and the mass difference between the two B[sub d] eigenstates has been measured to be[Delta]m[sub d]= 0.503[+-] 0.028[+-] 0.020 ps[sup -1].
