  • Tuesday, October 21
    • 9:00 AM 9:20 AM
      Tevatron experience. Physics modeling choices 20m
      - focus on experience, successes and limitations of the MC tools used (Resbos, PHOTOS, ...) - any other relevant aspects in this context
      Speaker: Jan Stark (Centre National de la Recherche Scientifique (FR))
      Slides
    • 9:30 AM 9:50 AM
      PDF uncertainty estimates 20m
      - give the basic setting (starting points for the two experiments) - discuss a basic procedure for systematics - ATLAS PDF ongoing studies - what can be done to lower the systematics (i.e. new NNPDF set, measuremnt with 7,8,13 TeV) - LHC data used to constrain the uncertainties, and how
      Speaker: Stefano Camarda (Deutsches Elektronen-Synchrotron (DE))
      Slides
    • 10:00 AM 10:20 AM
      Momentum calibration and recoil: experimental systematics (ATLAS/CMS) 20m
      This talk is on the muon momentum calibration, EM calibration and MET. Not on the methods but more on general problematics. - general differences between experiments Tevatron vs LHC (ATLAS vs CMS) - theoretical uncertainties on the Z lineshape-- i.e. FSR effect on lepton calibration - how port the calibrations from the Z to the W

      - give the basic setting ( powheg, RESBOS, tune: starting points for the experiments) - is the same between experiments ? - discuss a basic procedure for systematics - LHC data used to constrain the uncertainties, and how
      Speaker: Luca Perrozzi (Eidgenoessische Tech. Hochschule Zuerich (CH))
      Slides
    • 11:30 AM 11:50 AM
      Physics modeling : distributions to be published beyond Mw (discussion) 20m
      - other theoretical aspects not covered before (polarization, ...) - what we need to have to disentangle any discrepancies (i.e. on the theoretical syst between experiments) - what we need to publish to allow the theorists to help us to study how to lower the theoretical syst uncertainties - usefulness of other distributions (lepton Pt, boson pt)
