  1. Attivita’ di software+analisi fisica a Padova U. Gasparini,Padova, 4/9/06

  2. Agenda -  CSA06 (Computing -Software-Analysis challenge 2006: previsto in autunno) : prototipi da sviluppare, nostro coinvolgimento - analisi dati magnet test (possibili analisi comuni Tracker/mu sui dati dalla DAQ globale?) - Organizzazione ambiente di lavoro comune: risorse hardware & software - analisi di 'prima fisica' a LHC - preparazione per LHC startup workshop (prossima CMS week)

  3. CSA06: scopo/definizione E’ il primo test globale di ricostruzione/analisi nel framework finale (sia sw che infrastruttura di computing) di CMS (“LHC-like”): D.Acosta, CSA meeting 2/8/06 vedi dopo

  4. CSA06 More info (status, data handling/ organization, various technical details, meetings agenda/presentations…): Twiki page:

  5. CSA06: overall “expressions of interests” D.Acosta 23/8

  6. CSA06: data samples Pre-challenge phase well advanced: preparation of datasamples (up to “digis”) almost finalized Minimum bias (25M events, 081) t-tbar (5M events, all decay channels, 082) Z->mu+mu- (2M events, 082) W->e nu (4M events, 082) events selected in narrow range to illuminate 2 SMs Electroweak soup (5M events, 082) 2.6M W->l nu (xsec reduced 1/5) + 2.2M Drell-Yan (mass>15 GeV) + 0.1M H->WW (xsec increased 40X), all 3 charged lepton generations Soft Muon Soup (2M events, 082) 1M events inclusive muons in minbias + 1M events J/Psi production, with Pt_mu>4 preselection Jet calibration soup (~1M events, 082) dijet + Z+jet, various pt-hat ranges with weights to give JetMET event yield HLT soup (5M++ events, 082), W (charged leptons) + Drell-Yan (mass>20 GeV, charged leptons) + t-tbar (all modes) + dijets (pt-hat>350 GeV)

  7. Muon Analyses for CSA06 • Proposals for PRS/mu contributions to CSA06: • Alignment study with prompt muons from W and Z decays • Extraction of Wmn signal out of single-lepton datastream • Di-muon analysis, Z reconstruction and muon efficiency measurement from data • Extraction of J/Y signal and momentum calibration • => optional

  8. PTDR: Estimator from StandAlone muon fit (in ORCA; chambers randomly mis-aligned by  1 mm) ~2 fb-1 cambers misaligned By 1 mm chambers aligned 1. Alignment Madrid, Santander CSA06: reproduce this result In CMSSW, starting from a “HLT high pT lepton-stream” of ~ 5 M ev. (including 10-20 % of W  mn ) Datasamples; - 1 M Z 2m - 1 M W mn

  9. Extract ~ 2000 W out of a single-lepton datastream including ~ 1 Mevt of QCD ppm X events 2. Wmn Analysis Lint~12 nb-1 Padova Scope: - test HLT trigger efficiency - test isolation algorithms - show capability to isolate ‘standard candle’ with good purity (=> lumi measurement) - needed for alignment - may be used for jet calibration? Datasamples: - 1M ppm X preselected (MSEL=1, pthat=20, pTmu> 5) - 10 kevt W signal W Generator level

  10. 3. Di-Muon Analysis Extract Z signal from 1+2mu ‘high pT lepton’ datastream Florida,Purdue,FNAL,Madrid Scope: - test Z reconstruction with 1 and 2 identified muons - test procedures to measure efficiencies from data - high pT momentum calibration, mag.field effects Sample/code: - 1 M Z 2m - 1 M W mn (background) additional backg. from tt  single semileptonic

  11. - Extract ~2000 J/y signal out of 1 Mev pp 1m+X • Perform detailed study of momentum calibration • on a dedicated ~ 106 evt J/Psi sample 4. J/psi Calibration ~200 J/y / (10 nb-1) Scope: - understand/train of low pT triggers - muon identification in jet environment - momentum calibration, mag.field effects Sample/code: - 1 M J/psi pTmu1> 4. GeV pTmu2> 1. GeV (BUT 2ndm is NOT identified in ~50% of the cases) Spain, China groups interested

  16. MTCC analyses MTCC ‘phase 1’ (basically hardware/online,offline software integration test) completed: ~ 15 M trigger (7 TB data) taken(“local” and “global” runs, many different trigger conditions, B = 0 and “B on” data (up to 3.8 T)) A lot of detector specific work on-going… (see e.g. “DT/CSC cosmics analysis” meetings on: http: //indico.cern.ch/categoryDisplay.py?categId=20 )
