Available in PDF, EPUB and Kindle. Book excerpt: The angular distributions and the differential branching fraction of the decay B0→K*(892)0[mu]+[mu]- are studied using data corresponding to an integrated luminosity of 20.5 fb-1 collected with the CMS detector at the LHC in pp collisions at √s = 8 TeV. Additionally, from 1430 signal decays, the forward-backward asymmetry of the muons, the K*(892)0 longitudinal polarization fraction, and the differential branching fraction are determined as a function of the dimuon invariant mass squared. Our measurements are among the most precise to date and are in good agreement with standard model predictions.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The decay $ \mathrm{B}^{+} \to \psi(2 \mathrm{S}) \phi(1020) \mathrm{ K }^{+} $ is observed for the first time using data collected from pp collisions at $\sqrt{s} = $ 8 TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6 fb$^{-1}$. The branching fraction of this decay is measured, using the mode $\mathrm{B}^{+}\to \psi(2 \mathrm{S}) \mathrm{ K }^{+}$ as normalization, to be (4.0 $\pm$ 0.4 (stat) $\pm$ 0.6 (syst) $\pm$ 0.2 ($\mathcal{B})$)$\times$ 10$^{-6}$, where the third uncertainty is from the imprecision in the normalization channel.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We measure the?{sub b}° lifetime in the fully reconstructed decay?{sub b}° → J/??° using 10.4 fb−1 of p{bar p} collisions collected with the D0 detector at √s = 1.96 TeV. The lifetime of the topologically similar decay channel B° → J/? K{sub S}° is also measured. We obtain? (?{sub b}°) = 1.303 ± 0.075 (stat.) ± 0.035 (syst.) ps and? (B°) = 1.508 ± 0.025 (stat.) ± 0.043 (syst.) ps. Using these measurements, we determine the lifetime ratio of? (?{sub b}°)/? (B°) = 0.864 ± 0.052 (stat.) ± 0.033 (syst.).
Download or read book Measurement of the B sup 0 phi K sup 0 Decay Amplitudes written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With a sample of about 227 million B[bar B] pairs recorded with the BABAR detector at the PEP-II storage ring the authors perform a full angular analysis of the decay B[sup 0] --> [phi]K*[sup 0](892). They measure the branching fraction to be (9.2 [+-] 0.9 [+-] 0.5) x 10[sup 06] and determine the fractions of longitudinal and parity-odd transverse contributions as f[sub L] = 0.52 [+-] 0.05 [+-] 0.02 and F[sub [perpendicular]] = 0.22 [+-] 0.05 [+-] 0.02, respectively. The phases of the parity-even and parity-odd transverse amplitudes relative to the longitudinal amplitude are found to be [phi][sub [parallel]] = 2.34[sub -0.20][sup +0.23] [+-] 0.05 rad and [phi][sub [perpendicular]] = 2.47 [+-] 0.25 [+-] 0.05 rad, respectively. The authors measure five CP asymmetries which provide important limits on CP violation originating from new physics. They also observe the decay B[sup 0] --> [phi]K*[sup 0](1430).

Available in PDF, EPUB and Kindle. Book excerpt: This first open access volume of the handbook series contains articles on the standard model of particle physics, both from the theoretical and experimental perspective. It also covers related topics, such as heavy-ion physics, neutrino physics and searches for new physics beyond the standard model. A joint CERN-Springer initiative, the "Particle Physics Reference Library" provides revised and updated contributions based on previously published material in the well-known Landolt-Boernstein series on particle physics, accelerators and detectors (volumes 21A, B1,B2,C), which took stock of the field approximately one decade ago. Central to this new initiative is publication under full open access

Available in PDF, EPUB and Kindle. Book excerpt: Using data taken with the CLEO II detector, we present the first full angular analysis in the color-suppressed modes B[sup 0][yields] J/[psi] K*[sup 0] and B[sup+][yields] J/[psi] K*[sup+]. This leads to a complete determination of the decay amplitudes of these modes. In addition, we update the branching fractions for B[yields] J/[psi] K and B[yields] J/[psi] K*.
