  1. 88. Wmass,W and Z properties(Tevatron)
    Dr Marco Rescigno
    09/03/2010 08:30
  2. 60. Top Quark Production at the Tevatron
    Dr Alison Lister (Université de Genève)
    09/03/2010 08:50
    Experiment
    Ordinary
    Discovered in 1995 by CDF and D0, the top quark is the heaviest known elementary particle until today. Due to its short lifetime and its high mass, the top quark is an interesting particle to study. In this talk we will present the latest measurements related to top quark production, such as the cross section of ttbar and single top. Some searches for new particles with signatures similar...

  3. 58. Top Quark Properties at the Tevatron
    Dr Yvonne Peters (University of Manchester)
    09/03/2010 09:10
    Experiment
    Ordinary
    This talk will show several highlights of top quark properties measurements, like for example the top quark mass, top quark width and ttbar spin correlations. Furthermore, a selection of beyond the SM top quark searches, in context with top properties measurements, will be presented.

  4. 4. Measuring the running top-quark mass
    Prof. Peter Uwer (Humboldt-Universität zu Berlin)
    09/03/2010 09:30
    Theory
    We present the first direct determination of the running top-quark mass based on the total cross section of top-quark pair-production as measured at the Tevatron. Our theory prediction for the cross section includes various next-to-next-to-leading order QCD contributions, in particular logarithmically enhanced terms near threshold, the Coulomb corrections at two loops and all explicitly...

  5. 124. Diboson Production at the Tevatron
    Dr Ia Iashvili (SUNY Buffalo)
    09/03/2010 10:10
    Experiment
    Ordinary
    We present the latest results on the production of WW, WZ, Wgamma, Zgamma and ZZ events at the Fermilab Tevatron Collider. The results are based on the analyses of ~1 -- 5/fb of data collected in ppbar collisions at sqrt{s}=1.96~TeV by CDF and DO experiments during the Tevatron Run II. Analyses of the diboson production processes provide crucial test of the Standard Model, directly...

  6. 43. Tevatron Searches for New Physics with Leptons
    Dr Jonathan Hays
    09/03/2010 10:30
    The Fermilab Tevatron Collider experiments have now each collected almost 7 fb-1 of data, and are steadily increasing their sensitivity to physics beyond the standard model. In this talk, recent results from searches in final states containing leptons will be described.

  7. 127. Isolated leptons at HERA
    Dr Amita Raval

  8. 102. EW Measurements at High Q2 at HERA
    M. Stanislav Shushkevich (MPIM)
    09/03/2010 11:05
    Over 15 years of data taking at the HERA ep collider about 1 fb-1 was gathered in the H1 and ZEUS experiments for neutral and charge current deep inelastic processes at the center-of-mass energy of 320 GeV. This allows to provide the precise determination of the parton distribution functions in the proton and study of the EW effects using data from high Q2, where the contribution from W, Z...

  9. 50. SOFT WALLS: AN ALTERNATIVE SOLUTION TO THE ELECTROWEAK HIERARCHY
    Prof. Mariano Quiros (ICREA)
    09/03/2010 17:00
    Soft walls are alternative solutions (to RS ones) to the hierarchy problem in warped extra dimensions. Soft walls are generic models where extra scalars are propagating in the bulk and back react on the metric. They replace IR brane by a curvature singularity. Soft walls can provide very peculiar and unambiguous phenomenological features since KK modes (separated from the zero mode by a mass...

  10. 128. Cornering the Higgs at LEP
    Dr Kyle Cranmer
    09/03/2010 17:20
  11. 90. Tevatron searches: New Physics with photons and jets
    Dr Ben Brau

  12. 15. Gauge mediation : mass patterns review
    Dr Alberto Mariotti (VUB)
    09/03/2010 17:55
    We give a general formulation of semi-direct gauge mediation of supersymmetry breaking where the messengers interact with the hidden sector only through a weakly gauged group. We discuss the resulting MSSM gaugino masses and sfermion squared masses. We comment on how such mechanism can successfully be combined with other mediation schemes.

  13. 62. Non-standard SUSY spectra in gauge mediation
    Dr Stéphane Lavignac (IPhT Saclay)
    09/03/2010 18:30
    Theory
    Ordinary
    The experimental signatures of supersymmetric extensions of the Standard Model, such as the Minimal Supersymmetric Standard Model (MSSM), depend on the actual spectrum of superpartners, which in turn is determined by the mechanism responsible for the breaking of supersymmetry and for its mediation to the MSSM. An attractive possibility, known as gauge mediation, is that supersymmetry breaking...

  14. 49. Higgs in MSSM with dim-5 and 6 operators
    M. Igniatios Antoniadis (Ecole Polytechnique Centre de Physique Theorique (CPHT))
    09/03/2010 18:50
    Theory
    The presence of all R-parity conserving dimension-five and -six effective operators in the MSSM is analyzed in a model independent way, with emphasis on their implications to the Higgs sector and to LHC supersymmetry searches.
