  1. 274. Higgs Production in the MSSM
    Dr Christopher Jackson (Argonne National Laboratory)
    28/07/2009, 14:00
    Higgs Physics
    I will review the status of the production of the Minimal Supersymmetric Standard Model (MSSM) Higgs bosons at hadron colliders. The talk will include a brief introduction to the Higgs sector of the MSSM and a summary of the state-of-the-art in the calculations of the radiatively-corrected cross sections. I will also review the current bounds on the MSSM parameter space from searches for...

  2. 178. Search for Higgs in NMSSM and Hidden Valley models
    Dr Andy Haas (SLAC)

    Higgs Physics
    We report on a first search for production of Higgs bosons decaying into neutral long-lived particles (NLLP) which each decay to a bbbar pair, using 3.6 fb^-1 of data recorded with the D0 detector at the Fermilab Tevatron collider. We search for pairs of displaced vertices in the tracking detector at radii in the range 1.6--20 cm from the beam axis. No significant excess is observed above...

  3. 119. Search for a Light CP-Odd and Scaler Higgs in Upsilon Data
    Prof. Yury Kolomensky (University of California, Berkeley)
    28/07/2009, 15:00
    Higgs Physics
    We search for a light CP-odd Higgs boson, A^0, in the radiative decay of Y(3S) --> gamma A^0, A^0 --> tau+ tau-, tau+ --> e+ nu_e nubar_tau or tau+ --> mu+ nu_mu nubar_tau. The data sample contains 122 million Y(3S) events collected with the BaBar detector. We find no evidence for a narrow structure in the studied mass region of 4.03 < m_{A^0} < 10.10 GeV/c^2 and set the...

  5. 197. Search for the Higgs Boson in H->WW and WH to WWW(*) with the D0 Detector
    Dr Michael Kirby (Northwestern University)
    28/07/2009, 16:30
    Higgs Physics
    We present a search for the Standard Model Higgs boson produced via the WH to WWW(*) process at a center-of-mass energy of sqrt{s}=1.96 TeV with the D0 detector at the Fermilab Tevatron collider. We require two like-sign leptons (electrons or muons) with about 5 fb-1 of data. This channel provides significant sensitivity in the intermediate Higgs boson mass range. As well as inclusion of the...

  6. 259. Search for standard model Higgs boson in H->WW channel at CDF
    Dr Jennifer Pursley (University of Wisconsin)
    28/07/2009, 16:55
    Higgs Physics
    We present a search for standard model (SM) Higgs to WW production in dilepton plus missing transverse energy final states using approximately 5.0 fb-1 of integrated luminosity. In order to maximize sensitivity, the multivariate discriminants used to separate signal from background in the opposite-sign dilepton event sample have been independently optimized for final states with either zero,...

  7. 262. Combined upper limit on standard model Higgs boson production at the Tevatron
    Dr Nils Krumnack (Baylor University)
    28/07/2009, 17:20
    Higgs Physics
    A combination of several searches for standard model Higgs boson production at CDF using data samples up to 5fb-1 of integrated luminosity is performed. We calculate combined upper limits on the ratio of the Higgs boson cross section times branching ratio to its standard model prediction for Higgs boson masses between 100 GeV/c^2 and 200 GeV/c^2.
