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)

CSA06: data samples
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)
Pre-challenge phase well advanced: preparation of datasamples(up to “digis”) almost finalized

Muon Analyses for CSA06
Proposals for PRS/mu contributions to CSA06:
1) Alignment study with prompt muons from W and Z decays
2) Extraction of W signal out of single-lepton datastream
3) Di-muon analysis, Z reconstruction and muon efficiency measurement from data
4) Extraction of J/signal and momentum calibration=> optional

1. Alignment
PTDR:Estimator from StandAlone muon fit (in ORCA;chambers randomly mis-alignedby 1 mm)
~2 fb-1

cambersmisalignedBy 1 mmCSA06: reproduce this result
In CMSSW, starting from a“HLT high pT lepton-stream” of ~ 5 M ev.(including 10-20 % of W
Datasamples; - 1 M Z 2 - 1 M W

2. WAnalysisExtract ~ 2000 W out of a single-lepton datastream including~ 1 Mevt of QCD pp X events
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 X preselected (MSEL=1, pthat=20, pTmu> 5) - 10 kevt W signal

Lint~12 nb-1

3. Di-Muon Analysis
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 2 - 1 M W (background)
additional backg. from tt single semileptonic
Extract Z signal from 1+2mu ‘high pT lepton’ datastream

4. J/psi Calibration
- Extract ~2000 J/signal out of 1 Mev pp 1+X
- Perform detailed study of momentum calibration on a dedicated ~ 106 evt J/Psi sample
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. GeVpTmu2> 1. GeV
~200 J/ / (10 nb-1)
(BUT 2nd is NOT identified in ~50% of the cases)
Spain, China groups interested

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 )

MTCC analyses
- Can we developed cross-detectors analyses (e.g. barrel DT + Tracker) ?
- Preparing for MTCC “phase 2” (the true challenge: foreseen runs at 4 T under stable conditions..)
