  1. 184. D0 Mixing at the B-Factories
    Carlos Chavez (16509268522)

    Flavor Physics
    Parallel Talk
    We present results for D0-anti-D0 mixing using several different techniques from e+e- colliding-beam data recorded near sqrt(s) 10.6 GeV with the BaBar detector at the PEP-II storage rings at SLAC.

    Parallel Talk
    We search for anomalous charge asymmetries in the b to c transitions of both neutral and charged B mesons. Indirect CP violation in Bd and Bs mixing is studied using semileptonic decays. Direct CP violation in B+ decay is studied using exclusive decays to J/psi mesons. The results are based on a large data set of proton-antiproton collisions recorded by the Dzero detector operating...

  3. 193. The MFV-MSSM as a natural route to near-flavour-conservation in SUSY. Application to meson mixings

    Flavor Physics
    Parallel Talk
    We apply the effective field theory definition of Minimal Flavour Violation (MFV) to the MSSM, requiring the squark soft terms to become functions of the SM Yukawa couplings. For the case of meson oscillations in the DB=2 sector, we show that this approach leads to a striking increase of the predictivity of the model. In particular, we find (i) SUSY corrections to be...

  4. 246. The Higgs sector of the MSSM and B-Bbar mixing for large tan(beta)
    Dr Stephanie Trine (University of Karlsruhe)

    Parallel Talk
    A systematic analysis of supersymmetric effects in the B_d and B_s mass differences is performed in the large tan(beta) regime. Emphasis is laid on the impact of heavy sparticles on the effective Higgs-mediated FCNC amplitudes.

  5. 142. Bs-Bsbar mixing and Bs-->KK decays within supersymmetry
    Seungwon Baek (Korea Univ.)

    Flavor Physics
    Parallel Talk
    We consider the constraint of Bs-Bsbar mass difference, Delta m_s, on an MSSM scenario with large flavor mixing. Even with this constraint, we show that a large deviation from the SM in CP asymmetries of Bs-->KK decays is still possible, making this channel promising in search for supersymmetry.
