This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We report two preliminary measurements of the time dependence of B[sub d][sup 0]- B[sub d][sup 0] mixing using novel techniques with a sample of 150,000 hadronic Z[sup O] decays collected by the SLD experiment at the SLC. B decay vertices are reconstructed inclusively with a topological technique and the B hadron flavor at production is determined by exploiting the large left-right forward-backward asymmetry of Z[sup O][r-arrow] b[bar b] decays in combination with a jet charge technique. Two methods are used to tag the B flavor at decay. The first uses the charge of kaons attached to the B decay vertex and identified with the Cherenkov Ring Imaging Detector. The second measurement is based on the construction of a charge dipole of the topological vertices to separate the B[sub d][sup O]/B[sub d][sup 0] decays by exploiting the B[r-arrow] D cascade charge structure. The measurement of the oscillation frequency yields[Delta]m[sub d]= 0.58[+-] 0.07(stat)[+-]0.08(syst) ps[sup -1] and 0.56[+-] 0.08(stat)[+-]0.04(syst) ps[sup[minus]1] for the kaon and dipole tags respectively.

Book excerpt: We report two preliminary measurements of the time dependence of B{sub d}°- B{sub d}° mixing using novel techniques with a sample of 150,000 hadronic Z{sup O} decays collected by the SLD experiment at the SLC. B decay vertices are reconstructed inclusively with a topological technique and the B hadron flavor at production is determined by exploiting the large left-right forward-backward asymmetry of Z{sup O} → b {bar b} decays in combination with a jet charge technique.

The second measurement is based on the construction of a charge dipole of the topological vertices to separate the B{sub d}{sup O}/B{sub d}° decays by exploiting the B → D cascade charge structure. The measurement of the oscillation frequency yields [Delta]m{sub d} = 0.58 ± 0.07(stat)±0.08(syst) ps−1 and 0.56 ± 0.08(stat)±0.04(syst) ps−1 for the kaon and dipole tags respectively.

Download or read book A Measurement of the Time Dependence of B[sub D]-bar B[sub D] Mixing with Kaon Tagging written by and published by . This book was released on 2002 with total page pages. 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. The initial state B hadron flavor was determined using the large forward-backward asymmetry provided by the polarized electron beam of the SLC in combination with a jet charge technique and information from the opposite hemisphere. 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].

Download or read book Preliminary Measurement of Time-dependent B[sub D][sup 0]-B[sub D][sup 0] Mixing Using Topology and Charge Selected Semi-leptonic B Decays written by and published by . 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].

This book was released on 2004 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 350,000 hadronic Z[sup 0] 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[sup 0][yields] 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][sup 0] and[bar B][sub s][sup 0] decays exploits the B[sub s][sup 0][yields] D[sub s][sup -] 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][sup 0]-[bar B][sub s][sup 0] 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: 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]
