  1. 31. Flavour physics, supersymmetry and GUTs
    Prof. Ulrich Nierste (TTP, Karlsruhe Institute of Technology)
    16/03/2011 08:30
    Theory
    Ordinary
    The 2010 data on quark flavour physics reveal a considerable tension with the Standard Model. However, an excellent fit is found if one permits new physics in the amplitudes describing meson-antimeson mixing in the B_d and B_s systems. The corresponding global analysis disfavours the Standard Model at the level of 3.6 standard deviations and calls for new sources of CP violation in the...

  3. 46. Top polarisation at LHC and new physics
    Dr Jernej Kamenik ("Jozef Stefan" Institute)
    16/03/2011 09:15
    Experiment
    Ordinary
    Polarisation observables in top quark decays are sensitive probes of possible new physics contributions to the interactions of the heavy third generation quarks. Within an effective theory approach such new physics contributions can be classified in terms of several higher dimensional operators. We investigate the interplay between indirect constraints on such operators, coming mainly from...

  4. 112. Top properties from TeVatron
    Dr Fabrizio Margaroli (Purdue University)

  5. 66. Top-quark forward-backward asymmetry in Randall-Sundrum models
    Susanne Westhoff (Mainz University)
    16/03/2011 09:55
    Theory
    Ordinary
    I discuss the anomalously large asymmetry in top-antitop-quark production within Randall-Sundrum models. Kaluza-Klein gluons generically have the potential to generate a large forward-backward asymmetry at tree level. In models with an anarchic flavour structure, however, their coupling to the light quarks inside the proton is strongly suppressed. I show that even though this suppression is...

  6. 113. Flavour in Randall-Sundrum models
    Andreas Weiler (CERN Geneva Switzerland)

    Ordinary
  7. 99. Rare B and D Decays at BaBar
    Dr John Walsh (INFN, Pisa)
    16/03/2011 10:55
    Experiment
    Ordinary
    We present recent results on rare B and D decays from the Babar experiment. The focus will be on measurements that are sensitive to the presence of New Physics. Several flavour-changing-neutral-current channels have been investigated: we present results on the CP asymmetry in b -> s gamma, searches for B -> K nu nubar, B -> K tau tau and B0/D0 -> gamma gamma, as well as the branching fraction...

  8. 11. Heavy flavour physics at ATLAS
    Prof. Roger JONES (Lancaster University)
    16/03/2011 11:25
    Experiment
    Ordinary
    The QCD production of Quarkonia and high-PT B-hadrons are important processes as a probe of perturbative QCD. High-PT B-hadrons also form a significant background to many new physics channels at the LHC. The inclusive production of the J/psi and Upsilon mesons is studied in the dimuon decay mode. The double- differential cross section is measured with respect to the transverse momentum and...
