    A Review of Bs Mixing: Past, Present and Future

    Get PDF
    We review the experimental status of Bs mixing. After a brief historical overview, current studies of the time dependence of Bs oscillations are described, with an emphasis on the different experimental techniques used by the ALEPH, CDF, DELPHI, OPAL, and SLD Collaborations. To conclude, the outlook for future experiments is presented.Comment: Paper submitted to proceedings of the 3rd International Conference on B Physics and CP Violation, Taipei, Dec.3-7, 1999; 8 pages, 4 figure

    Electroweak and Heavy Flavor Physics at SLD

    Get PDF
    We review recent electroweak and B physics results obtained in polarized e+e- interactions at the SLC by the SLD experiment. Unique and precise measurements of the electroweak parameters Ae, Ab, Ac, Rb and Rc provide powerful constraints on the Standard Model. The excellent 3-D vertexing capabilities of SLD are further exploited to extract precise B+ and B0 lifetimes, as well as measurements of the time evolution of B0-B0-bar mixing.Comment: 11 pages, 5 figures. Presented at the Workshop on Physics at the First Muon Collider and at the Front End of a Muon Collider, 6-9 November 1997, Fermilab, Batavia, I

    B0s Oscillation Results

    Get PDF
    We review new studies of the time dependence of B0s - B0s-bar mixing by the ALEPH, DELPHI and SLD Collaborations, with an emphasis on the different analysis methods used. Combining all available results yields a preliminary lower limit on the oscillation frequency of dms > 14.4 ps-1 at the 95% C.L.Comment: 4 pages, 2 figures, contributed to ICHEP2002 proceeding

    Rare Hadronic and Radiative Penguin B Decays at BaBar

    Get PDF
    We report recent results in the study of rare hadronic and radiative penguin decays of B mesons. These results are based on a sample of 23 million B B-bar pairs collected by the BaBar Collaboration at the SLAC PEP-II e+e- B Factory.Comment: 7 pages, 2 figures; Contributed to the Proceedings of the 5th KEK Topical Conference: Frontiers In Flavor Physics (KEKTC5), 20-22 Nov 2001, Tsukuba, Ibaraki, Japa

    Search for Contact Interactions in the Dimuon Final State at ATLAS

    Get PDF
    The Standard Model has been successful in describing many fundamental aspects of particle physics. However, there are some remaining puzzles that are not explained within the context of its present framework. We discuss the possibility to discover new physics in the ATLAS Detector via a four-fermion contact interaction, much in the same way Fermi first described Weak interactions. Using a simple ratio method on dimuon events, we can set a 95% C.L. lower limit on the effective scale Lambda = 7.5 TeV (8.7 TeV) for the constructive Left-left Isoscalar Model of quark compositeness with 100 pb^-1 (200 pb^-1) of data at sqrt{s} = 10 TeV.Comment: To be published in the proceedings of DPF-2009, Detroit, MI, July 2009, eConf C09072

    B Physics at SLD

    We review recent BB physics results obtained in polarized e+e−e^+ e^- interactions at the SLC by the SLD experiment. The excellent 3-D vertexing capabilities of SLD are exploited to extract precise \bu and \bd lifetimes, as well as measurements of the time evolution of Bd0−Bd0ˉB^0_d - \bar{B^0_d} mixing.Comment: 7 pages, 4 figure

    Highlights of the SLD Physics Program at the SLAC Linear Collider

    Get PDF
    Starting in 1989, and continuing through the 1990s, high-energy physics witnessed a flowering of precision measurements in general and tests of the standard model in particular, led by e+e- collider experiments operating at the Z0 resonance. Key contributions to this work came from the SLD collaboration at the SLAC Linear Collider. By exploiting the unique capabilities of this pioneering accelerator and the SLD detector, including a polarized electron beam, exceptionally small beam dimensions, and a CCD pixel vertex detector, SLD produced a broad array of electroweak, heavy-flavor, and QCD measurements. Many of these results are one of a kind or represent the world's standard in precision. This article reviews the highlights of the SLD physics program, with an eye toward associated advances in experimental technique, and the contribution of these measurements to our dramatically improved present understanding of the standard model and its possible extensions.Comment: To appear in 2001 Annual Review of Nuclear and Particle Science; 78 pages, 31 figures; A version with higher resolution figures can be seen at http://www.slac.stanford.edu/pubs/slacpubs/8000/slac-pub-8985.html; Second version incorporates minor changes to the tex

    ATLAS Style Guide

    This is a compendium of rules, recommendations, information and advice for writing papers and notes within the ATLAS Collaboration at the CERN Large Hadron Collider. It covers what to include in the paper, and some general guidelines and specific points about writing a scientific paper. There are sections on the use of English (though it is not a guide to grammar), punctuation, and typography. Advice about the use of LATEX is also given
