Book excerpt: The BABAR experiment has been taking data since about one year. Physics results, complementary to those described in [1], are presented: various measurements of the neutral and charged B mesons lifetimes, the B° mixing frequency, the mistag fractions, and the B --> D{sub s}{sup (*)}X and B° --> D{sub s}{sup (*)+} D{sup *-} branching ratios. Some prospects for the close future are shown. All the numbers given here are preliminary.

Download or read book B Physics Cp Violation 99 3rd Intl Conf written by Wei Shu Hou and published by World Scientific. This book was released on 2000-12-29 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: CP violation was first observed in 1964, but only in 1999 did we gain much greater experimental insight. Direct CP violation finally appeared in the form of ε′/ε in the K system. Indirect CP violation in B → J/Ψ Ks decay, the raison d'être for construction of e+e- B factories, was first sniffed out at the proton-antiproton collider. The asymmetric B factories — BABAR at SLAC and BELLE at KEK — were completed, while the symmetric B factory at Cornell was upgraded to CLEO-III. It seems that everyone is positioning himself for the great competition on “B Physics and CP Violation”, racing to unravel the Kobayashi-Maskawa matrix, especially the size and origin of CP phases. The change of millennium provides a dramatic backdrop.To have intensive discussions at the technical level, to create broader interest in the subject, and to maximize interaction between experimenters and theorists, this book starts with the status of B factories: accelerator, detector and physics analysis. Following an overview of B physics and the CKM matrix, it delves into the details of lifetime, spectroscopy and decays, with even more specialized discussions on rare decays, direct and indirect CP violation, factorization and final state interactions, determination of unitarity phases, etc. Topics on ε′/ε, rare K decay, charm and hyperon systems, and various T, CP and CPT tests are also discussed at length. The book closes with the outlook for hadron machines and the prospects for new physics. A special feature is that there are two summary talks, one on experiment and the other on theory. The book is further augmented by two dozen excellent contributed talks.

Download or read book The First Physics Results From BaBar written by and published by . This book was released on 2001 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The BaBar experiment and the PEP-II accelerator at SLAC started to take data on May 26, 1999. By the time of this conference, the recorded integrated luminosity was 20 fb−1, of which 8 fb−1 were analyzed to provide a first set of physics results. This talk reviews the first measurement of sin 2[beta] and the study of B meson decays to charmonium modes and 2-body charmless decays. Complementary results were presented by the BaBar Collaboration at this conference and are reviewed in [1].

Book excerpt: The BABAR detector, which operates at the SLAC PEP-II asymmetric e[sup+]e[sup -] collider at energies near the[Upsilon](4S) resonance, started operation on the 26th of May 1999. They present the first study of sin2[beta], with samples of B[sup 0][yields] J/[psi] K[sub s][sup 0] and B[sup 0][yields][psi](2S) K[sub 2][sup 0] decays, using 9.0 fb[sup -1] of data recorded between January and July 2000 at the[Upsilon](4S) resonance and 0.8 fb[sup -1] recorded 40 MeV below the[Upsilon](4S) resonance. A preliminary result of sin2[beta]= 0.12[+-] 0.37(stat)[+-] 0.09(syst) was obtained. Details of the analysis are given. Moreover, they present measurements of charged and neutral B meson lifetimes and B[sup 0][bar B][sup 0] oscillation frequency.
Download or read book The Physics of the B Factories written by Adrian Bevan and published by Springer. This book was released on 2016-10-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive work thoroughly introduces and reviews the set of results from Belle and BaBar - after more than two decades of independent and complementary work - all the way from the detectors and the analysis tools used, up to the physics results, and the interpretation of these results. The world’s two giant B Factory collaborations, Belle at KEK and BaBar at SLAC, have successfully completed their main mission to discover and quantify CP violation in the decays of B mesons. CP violation is a necessary requirement to distinguish unambiguously between matter and antimatter. The shared primary objective of the two B Factory experiments was to determine the shape of the so-called unitarity triangle, an abstract triangle representing interactions of quarks, the elementary constituents of matter. The area of the triangle is a measure of the amount of CP violation associated with the weak force. Many other measurements have been performed by the B Factories and are also discussed in this work.

Book excerpt: A search is performed for mixing and CP violation in D[sup 0] decays from a 57 fb[sup -1] dataset acquired by the Babar experiment near the Upsilon(4S). The time-dependence is measured of wrong-sign decays D[sup 0] --> K[sup +] [pi][sup -] and also the lifetime ratios [tau](D[sup 0] --> K[sup -][pi][sup +])/[tau](D[sup 0] --> K[sup -]K[sup +]) and [tau](D[sup 0] --> K[sup -][pi][sup +])/[tau](D[sup 0] --> [pi][sup -][pi][sup +]). For the decays D[sup 0] --> K[sub s][sup 0]K[sup [+-]][pi][sup -] and D[sup 0] --> K[sub s][sup 0]K[sup +]K[sup -], preliminary measurements are presented of their branching fractions relative to that of D[sup 0] --> K[sub s][sup 0][pi][sup +][pi][sup -], together with an analysis of their Dalitz plot distributions.
