9:00 AM Tevatron experience. Physics modeling choices - Jan Stark (Centre National de la Recherche Scientifique (FR))
Tevatron experience. Physics modeling choices
- Jan Stark (Centre National de la Recherche Scientifique (FR))
9:00 AM - 9:20 AM
- focus on experience, successes and limitations of the MC tools used (Resbos, PHOTOS, ...) - any other relevant aspects in this context
9:30 AM PDF uncertainty estimates - Stefano Camarda (Deutsches Elektronen-Synchrotron (DE))
PDF uncertainty estimates
- Stefano Camarda (Deutsches Elektronen-Synchrotron (DE))
9:30 AM - 9:50 AM
- 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
10:00 AM Momentum calibration and recoil: experimental systematics (ATLAS/CMS) - Mariarosaria D'Alfonso (CERN)
Momentum calibration and recoil: experimental systematics (ATLAS/CMS)
- Mariarosaria D'Alfonso (CERN)
10:00 AM - 10:20 AM
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
10:30 AM Coffee break
Coffee break
10:30 AM - 11:00 AM
11:00 AM Vector boson transverse momentum distributions - Luca Perrozzi (Eidgenoessische Tech. Hochschule Zuerich (CH))
Vector boson transverse momentum distributions
- Luca Perrozzi (Eidgenoessische Tech. Hochschule Zuerich (CH))
11:00 AM - 11:20 AM
- 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
11:30 AM Physics modeling : distributions to be published beyond Mw (discussion) - (TBC) Maarten Boonekamp (CEA/IRFU,Centre d'etude de Saclay Gif-sur-Yvette (FR))
Physics modeling : distributions to be published beyond Mw (discussion)
- (TBC) Maarten Boonekamp (CEA/IRFU,Centre d'etude de Saclay Gif-sur-Yvette (FR))
11:30 AM - 11:50 AM
- 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)
