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 400,000 hadronic Z° decays collected by the SLD experiment at the SLC between 1996 and 1998. 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 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 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The time dependence of B[sub d][sup 0]-B[sub d][sup 0] mixing has been measured using a sample of 150,000 hadronic Z[sup 0] decays collected by the SLD experiment at the SLC between 1993 and 1995. The analysis identifies the semileptonic decays of B mesons with high (p, p[sub t]) leptons and reconstructs the B meson decay length and charge by vertexing the lepton with a partially reconstructed D meson. Vertex charge is used to enrich the selection of neutral over charged B mesons. This method results in a sample of 581 neutral decays with high charge purity. The B candidate is tagged at production with a combined tag that exploits the large polarized b forward-backward asymmetry in conjunction with the opposite hemisphere b jet charge. The final state is tagged by the sign of the high (p, p[sub t]) lepton. From their preliminary analysis the authors find a mass difference between the two B[sub d][sup 0] mass eigenstates of, [Delta]m[sub d]= 0.452[+-] 0.074(stat)[+-] 0.049(syst) ps[sup[minus]1].

Download or read book Search for Bs Mixing with Inclusive Leptons at SLD. written by and published by . This book was released on 2003 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have performed a sensitive search for B{sub s}° - {bar B}{sub s}° mixing using a sample of 400,000 hadronic Z° decays collected by the SLD experiment at the SLC between 1996 and 1998. B{sub s}° and {bar B}{sub s}° events were produced by Z° 2!b{bar b} decays where each side hadronized independently to b hadrons. The analysis determines the b hadron flavor at production by exploiting the large polarized forward-backward asymmetry of the b quark as well as information from the hemisphere opposite that of the reconstructed B decay. The final state b quark flavor is determined by the charge of a high p{sub T} lepton. A novel, highly efficient vertexing technique has been developed to locate the B decay vertex by exploiting the high p{sub T} lepton and the semileptonic decay topology. No significant mixing signal was found and the following ranges of the oscillation frequency of B{sub s}°-{bar B}{sub s}° mixing are excluded at 95% CL from the analysis presented in this thesis: [Delta]m{sub s}

Download or read book Search for B0(S) Anti-B0(S) Oscillations at SLD. written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present preliminary results on the time dependence of B[sub s][sup 0] -[bar B][sub s][sup 0] and B[sub d][sup 0] -[bar B][sub d][sup 0] mixing using a sample of 400,000 hadronic Z[sup 0] decays collected by the SLD experiment at the SLC. The analyses take advantage of the excellent decay length resolution of the CCD vertex detector. The B or[bar B] production flavor is determined by exploiting the large forward-backward asymmetry of polarized Z[sup 0][yields] b[bar b] decays. This flavor tag is enhanced by incorporating additional information from the hemisphere opposite that of the reconstructed B decay. The B[sub d][sup 0] -[bar B][sub d][sup 0] mixing analysis uses the charge of high momentum kaons to identify the B or[bar B] decay flavor. The result is[Delta]m[sub d]= 0.503[+-] 0.028(stat)[+-] 0.020(syst) ps[sup -1]. The results of three separate B[sub s][sup 0] -[bar B][sub s][sup 0] mixing analyses are presented. These analyses determine the B decay flavor using the lepton charge in B semileptonic decays, the charge of fully reconstructed D[sub s] decays, and the charge difference between topologically reconstructed B and D decays. The three analyses are combined to set a lower limit on the B[sub s][sup 0] -[bar B][sub s][sup 0] oscillation frequency of 12.0 ps[sup -1] at 95% CL.

This book was released on 2001 with total page 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][sup 0] -[bar B][sub s][sup 0] mixing using a sample of 400,000 hadronic Z[sup 0] decays collected by the SLD experiment at the SLC during the 1996-98 run. In this analysis, B[sub s][sup 0] mesons are partially reconstructed by combining a fully reconstructed D[sub s] with other B[sub s][sup 0] decay tracks. The D[sub s] decays are reconstructed via the[phi][pi] and K*K channels. The b-hadron flavor at production is determined by exploiting the large forward-backward asymmetry of polarized Z[sup 0][yields] b[bar b] decays as well as information from the hemisphere opposite to the reconstructed B decay. The flavor of the B[sub s][sup 0] at the decay vertex is determined by the charge of the D[sub s]. A total of 361 candidates passed the final event selection cuts. This analysis excludes the following values of the B[sub s][sup 0]-[bar B][sub s][sup 0] mixing oscillation frequency:[Delta]m[sub s]

Available in PDF, EPUB and Kindle. Book excerpt: Based on an 87-fb{sup -1} dataset collected by the Babar detector at the PEP-II asymmetric-energy B-Factory, a search for D{sup 0}-{bar D}{sup 0} mixing has been made using the semileptonic decay modes D*{sup +} {yields} {pi}{sup +}D{sup 0}, D{sup 0} {yields} Ke{nu} (+c.c.). The use of these modes allows unambiguous flavor tagging and a combined fit of the D{sup 0} decay time and D*{sup +}-D{sup 0} mass difference ({Delta}M) distributions. The high-statistics sample of unmixed semileptonic D{sup 0} decays is used to model the {Delta}M distribution and time-dependence of mixed events directly from the data. Neural networks are used to select events and reconstruct the D{sup 0}. A result consistent with no charm mixing has been obtained, R{sub mix} = 0.0023 {+-} 0.0012 {+-} 0.0004. This corresponds to an upper limit of R{sub mix}
