Book excerpt: The authors present a simultaneous measurement of the {bar B}° lifetime [tau](B°) and mixing parameter [Delta]m{sub d}. They use a sample of about 50000 {bar B}° --> D* 1 {anti {nu}}(l) partially reconstructed decays identified with the BABAR detector at the PEP-II storage ring at SLAC, where the flavor of the other B meson is determined from the charge of another high momentum lepton in the same event. The preliminary results are: tau(B°) = (1.50 ± 0.008(stat.) ± 0.030(syst.)) ps, [Delta]m{sub d} = (0.523 ± 0.004(stat.) ± 0.007(syst.)) p{sup s}( -1).

This book was released on 2002 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: We measure the B° lifetime [tau]{sub b°} and the B°-{bar B}° oscillation frequency [Delta]m{sub d} with a sample of approximately 14,000 exclusively reconstructed B{sup 0} 2!D*− l [nu]{sub {ell}} signal events, selected from 23 million B{bar B} pairs recorded at the [Upsilon](4S) resonance with the BABAR detector at the Stanford Linear Accelerator Center. The decay position of the other B is determined with the remaining tracks in the event, and its b-quark flavor at the time of decay is determined with a tagging algorithm that exploits the correlation between the flavor of the b-quark and the charges of its decay products. The lifetime and oscillation frequency are measured simultaneously with an unbinned maximum-likelihood ([Delta]t) that uses, for each event, the measured difference in decay times of the two B mesons ([Delta]t), the calculated uncertainty on [Delta]t, the signal and background probabilities, and b-quark tagging information for the other B. The results are [tau]{sub B{sup 0}} = (1.523{sub -0.023}{sup +0.024} ± 0.022) ps and [Delta]m{sub d} = (0.492 ± 0.018 ± 0.013) ps−1.

Book excerpt: We measure the B° lifetime [tau]{sub B°} and the B°-{bar B}° oscillation frequency [Delta]m{sub d} with a sample of approximately 14,000 exclusively reconstructed B{sup 0} 2!D*− l [nu]{sub {ell}} signal events, selected from 23 million B{bar B} pairs recorded at the [Upsilon](4S) resonance with the BABAR detector at the Stanford Linear Accelerator Center.

Available in PDF, EPUB and Kindle. Book excerpt: The authors present the first measurement of the B{sub s}°-{bar B}{sub s}° oscillation frequency [Delta]m{sub s}. They use 1 fb−1 of data from p{bar p} collisions at √s = 1.96 TeV collected with the CDF II detector at the Fermilab Tevatron. The sample contains signals of 3600 fully reconstructed hadronic B{sub s} decays and 37,000 partially reconstructed semileptonic B{sub s} decays. They measure the probability as a function of proper decay time that the B{sub s} decays with the same, or opposite, flavor as the flavor at production and they find a signal consistent with B{sub s}°-{bar B}{sub s}° oscillations. The probability that random fluctuations could produce a comparable signal is 0.2%. Under the hypothesis that the signal is due to B{sub s}°-{bar B}{sub s}° oscillations, they measure [Delta]m{sub s} = 17.31{sub -0.18}{sup +0.33}(stat.) ± 0.07(syst.) ps−1 and determine.

Book excerpt: Flavor oscillations of neutral B mesons have been studied with e+e- annihilation data collected at center of mass energies near the [gamma](4S) at the PEP-II asymmetric collider with the BABAR detector. One B0 is fully reconstructed in a hadronic decay to a flavor eigenstate. The flavor of the other B in the event is determined using an inclusive tagging algorithm which exploits the correlations between the flavor of the b quark and the charges of its decay products. By fitting the decay-time distribution of the observed mixed and unmixed final states, the oscillation frequency, [Delta]md, is determined to be 0.516 +/- 0.016 (stat.) +/- 0.010 (syst.) ps-l.

Available in PDF, EPUB and Kindle. Book excerpt: Lifetime measurements for B0 and B+ are presented using semileptonic decays of B mesons from 360 pb-1 of data collected by CDF's lepton plus displaced track trigger. The decays B 2!l[nu]DX, where D is either D +, D0, or D* +, are partially reconstructed from a muon or electron, a displaced track, and a fully reconstructed charm meson. The B 0 and B+ lifetimes are obtained from an unbinned maximum-likelihood fit to the proper decay length distributions. The measured lifetimes are [tau]B 0 = 1.527 ± 0.012(stat.) ± 0.023(syst.)ps and [tau]B + = 1.629 ± 0.013(stat.) ± 0.025(syst.)ps.

Book excerpt: The authors report the observation of B{sub s}°-{bar B}{sub s}° oscillations from a time-dependent measurement of the B{sub s}°-{bar B}{sub s}° oscillation frequency [Delta]m{sub s}. Using a data sample of 1 fb−1 of p{bar p} collisions at √s = 1.96 TeV collected with the CDF II detector at the Fermilab Tevatron, they find signals of 5600 fully reconstructed hadronic B{sub s} decays, 3100 partially reconstructed hadronic B{sub s} decays, and 61,500 partially reconstructed semileptonic B{sub s} decays. They measure the probability as a function of proper decay time that the B{sub s} decays with the same, or opposite, flavor as the flavor at production, and they find a signal for B{sub s}°-{bar B}{sub s}° oscillations. The probability that random fluctuations could produce a comparable signal is 8 x 10−8, which exceeds 5[sigma] significance. They measure [Delta]m{sub s} = 17.77 ± 0.10(stat) ± 0.07(syst) ps−1 and extract.

Available in PDF, EPUB and Kindle. Book excerpt: Flavor oscillations of neutral B mesons have been studied in ee− annihilation data collected with the BABAR detector at center-of-mass energies near the [Upsilon](4S) resonance. The data sample used for this purpose consists of events in which one B° meson is reconstructed in a hadronic decay mode, while the flavor of the recoiling B° is determined with a tagging algorithm that exploits the correlation between the flavor of the heavy quark and the charges of its decay products. From the time development of the observed mixed and unmixed final states we determine the B°-{bar B}° oscillation frequency [Delta]m{sub d} to be 0.516 ± 0.016(stat) ± 0.010(syst) ps−1.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present a measurement of the B{sub s}° lifetime in fully and partially reconstructed B{sub s}° → D{sub s}°([phi][pi]−)X decays in 1.3 fb−1 collected in p{bar p} collisions at √s = 1.96 Tev by the CDF II detector at the Fermilab Tevatron. They measure [tau](B{sub s}°) = 1.518 ± 0.041 (stat.) ± 0.027 (syst.) ps. The ratio of this result and the world average B° lifetime yields [tau](B{sub s}°)/[tau](B°) = 0.99 ± 0.03, which is in agreement with recent theoretical predictions.

Available in PDF, EPUB and Kindle. Book excerpt: Data collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC are used to measure the lifetimes of the B° and B mesons. The data sample consists of 8.3 fb−1 collected near the [Upsilon](4S) resonance. B° and B mesons are fully reconstructed in several exclusive hadronic decay modes to charm and charmonium final states. The B lifetimes are determined from the flight length difference between the two B mesons.
