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 scopo/definizione
E il primo test globale di ricostruzione/analisi
nel framework finale (sia sw che infrastruttura
di computing) di CMS (LHC-like)

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
• gt optional

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

2. W?mn Analysis
Lint12 nb-1
Padova
Scope - test HLT trigger efficiency -
test isolation algorithms - show capability
to isolate standard candle with good
purity (gt lumi measurement) - needed for
alignment - may be used for jet
calibration? Datasamples - 1M pp? m X
preselected (MSEL1, pthat20, pTmugt 5)
- 10 kevt W signal
W
Generator level

3. Di-Muon Analysis
Extract Z signal from 12mu 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
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
pTmu1gt 4. GeV pTmu2gt 1. GeV
(BUT 2nd m 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?cat
egId20 )

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..)
