Available in PDF, EPUB and Kindle. Book excerpt: We have measured the time-dependent decay rate for the process B [yields] J/[psi] K*[sup 0](892) in a sample of about 88 million [Upsilon](4S) [yields] B[bar B] decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. In this sample we study flavor-tagged events in which one neutral B meson is reconstructed in the J/[psi]K*[sup 0] or J/[psi] [bar K]*[sup 0] final state. We measure the coefficients of the cosine and sine terms in the time-dependent asymmetries for J/[psi]K*[sup 0] and J/[psi][bar K]*[sup 0], find them to be consistent with the Standard Model expectations, and set upper limits at 90% C.L. on the decay amplitude ratios A([bar B][sup 0] [yields] J/[psi]K*[sup 0])/A(B[sup 0] [yields] J/[psi]K*[sup 0])

Book Synopsis Measurement of Decay Amplitudes of B to Ccbar K* with an Angular Analysis, for Ccbar by : B. Aubert
Download or read book Measurement of Decay Amplitudes of B to Ccbar K* with an Angular Analysis, for Ccbar written by B. Aubert and published by . This book was released on 2006 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: We perform the first three-dimensional measurement of the amplitudes of B {yields} {psi}(2S)K* and B {yields} {chi}{sub c1}K* decays and update our previous measurement for B {yields} J/{psi} K*. We use a data sample collected with the BABAR detector at the PEP-II storage ring, representing 232 million produced B{bar B} pairs. The longitudinal polarization of decays to the 1{sup ++} {chi}{sub c1} meson together with a K* meson, is found to be larger than that for the decay to the 1{sup --} {Psi} mesons. No direct CP-violating charge asymmetry is observed.

Book Synopsis Measurement of the B_d0 Lifetime Using B_d0 to J/psi K0_S Decays at Dzero by : Paul W. Balm
Download or read book Measurement of the B_d0 Lifetime Using B_d0 to J/psi K0_S Decays at Dzero written by Paul W. Balm and published by . This book was released on 2004 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes a measurement of the B{sub d}{sup 0} lifetime in the decay to (J/{psi}K{sub S}{sup 0}), using 114 pb{sup -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{sub d}{sup 0} decays to (J/{psi}K{sub S}{sup 0}).

Available in PDF, EPUB and Kindle. Book excerpt: We present measurements of the linear polarization amplitudes and the strong relative phases that describe the flavor-untagged decays B{sub d} → J/[Psi] K* and B{sub s} → J/[Psi][phi] in the transversity basis. We also measure the mean lifetime of the B{sub s} mass eigenstates and the lifetime ratio. The analyses are based on approximately 2.8 fb−1 of data recorded with the D0 detector. From our measurements of the angular parameters we conclude that there is no evidence for a deviation from flavor SU(3) symmetry for these decays and that the factorization assumption is not valid for the B{sub d} → J/[Psi] K* decay.

Download or read book Measurement of Inclusive and Exclusive B Decays to Charmonium with BaBar written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Using 8.5M BB events recorded by the BABAR detector the yield of inclusive J[psi], the branching ratios of[psi](2S) and x[sub c] are presented. Combining the charmonium state with either a K[sup+-], K[sub s][sup 0], K*[sup+-] exclusive B decays are reconstructed and their branching ratios determined. Using the fully reconstructed decays, both the B[sup 0] B[sup+-] masses and their difference is measured. Finally the contributions of CP even and odd amplitudes in the decay B[yields] J/[psi] K* are determined from an angular analysis.

Download or read book Measurement of B[sup 0]/Bbar[sup 0] [right Arrow]J/[psi] K(0 Over S) Decay Asymmetry Using Same-side B-flavor Tagging written by and published by . This book was released on 2000 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a measurement of the time-dependent asymmetry in the rate for [anti B][sup 0] versus B[sup 0] decays to J/[psi]K[sup 0][sub s]. The data sample consists of 198 [+-] 17 B[sup 0]/[anti B][sup 0] decays collected by the CDF detector in p[anti p] collisions at the Fermilab Tevatron, where the initial b flavor has been determined by a same-side flavor tagging technique. This asymmetry is interpreted in the Standard Model as a measurement of the CP-violation parameter sin(2[beta]). Our analysis results in sin(2[beta]) = 1:8 [+-] 1:1(stat) [+-] 0:3(syst).
