1. Monika Grothe, DQM for MC from EWK PAG, Sep 1 2009 1 DQM for MC from EWK PAG Monika Grothe U Wisconsin September 1 2009 Currently 3 modules: 1.EwkDQM in CMSSW/DQM/Physics (authors M. Anderson, W. Parker) 2.WmunuValidator in CMSSW/ElectroWeakAnalysis/Wmumu (M. Cepeda, J.Alcaraz) 3.ValidAnalyzer in Wisconsin cvs (M. Anderson, K. Flood)

2. Monika Grothe, DQM for MC from EWK PAG, Sep 1 2009 2 EwkDQM EWK monitor for PVT Available in CMSSW/DQM/Physics Runs in 3.1.x Require single lepton HLT and lepton pT>20 Leading and sub-leading e, mu Leading & sub-leading jet Inv mass & trans mass, MET, vertex No taus (well covered by POG) Only basic reco objects, no PAT Only lepton candidates, no W’s or Z’s Not limited to any single EWK channel Can be used on MC and data Can be used with low lumi samples Q: Will the resulting histos be avaliable via the DQM GUI ? Couldn’t find this for Summer 09 preprod samples on which code was apparently run

3. Monika Grothe, DQM for MC from EWK PAG, Sep 1 2009 3 WmunuValidator Sample for Validation (eg: WMuNu from Summer09) Sample for Validation (eg: WMuNu from Summer09) FILTER  Get Histograms using WMuNuSelector with WMuNuAODValidator.py FILTER  Get Histograms using WMuNuSelector with WMuNuAODValidator.py Reference Sample (eg: WMuNu from Summer08) Reference Sample (eg: WMuNu from Summer08) MACRO  Compare histograms using WMuNuValidatorMacro MACRO  Compare histograms using WMuNuValidatorMacro Analysis specific Plot all quantities used in selection before cuts and after (n-1) cuts Compare resulting histograms to reference histograms by running root macro Available in CMSSW/ElectroWeakAnalysis/Wmumu Was used to spot differences between Summer08 and Summer09 production EWK PAG plans to have similar modules for Wenu, Zee, Zmumu Q: Can this be interfaced to the DQM framework for displaying via the Web ? How ?

4. Monika Grothe, DQM for MC from EWK PAG, Sep 1 2009 4 ValidAnalyzer CMSSW module residing in Wisconsin cvs Runs in a half-automated way Finds newly produced MC samples at Wisconsin Tier-2 as they appear Produces plots that are being displayed on http://www.hep.wisc.edu/cms/comp/DataQualMgmt/Images/ Plots for e, mu, photon, jets, ETmiss, tracks Plots on resolution, generated and reconstructed kinematic variables Could be used also for MC production at other EWK Tier-2’s Q: Of interest for general DQM ?

5. Monika Grothe, DQM for MC from EWK PAG, Sep 1 2009 5 Summary Three different validation modules used by EWK PAG Are complementary: EwkDQM plots very basic reco quantities for leptons, jets, vertex quantities, ETmiss WmunuValidator analysis-specific, will have something similar for Zmumu, Zee, Wenu ValidAnalyzer MC-specific, checks basic reco and gen quantities and makes plots available on Web page
