CMSIM

OSCAR

development of first “full off-line” analyses (i.e. beyond HLT) onpredefined benchmark channels

Post DAQ TDR activity

After completion of DAQ TDR (Dec.2002), main emphasis this year will be on:

- switch to GEANT4 simulation, reproducing/improving in OSCAR+ORCA (full C++) chain the known HLT results from CMSIM + ORCA - by- products: - new Detector Description Database (DDD) system - refine sub-detectors geometries (when needed)

[ e.g. for BMU: - insert proper staging between SL - insert chimneys - include “+ve” “-ve” chamber readout ]

- have consistent ORCA code between MC and TestBeam data analysis environment

Post DAQ TDR activity

-develop first full off-line analyses down to O(10-5-10-7) Hz rate on few relevant benchmark signals

- significant training/test of the software + computing system

HLT outpupt, di-mu stream ( 3 Hz)Low lumi (DAQ TDR, ch.15)

H WW 22(see M.Zanetti’s talk)

U.Gasparini 10/04/03 6

Post DAQ TDR activityCurrent choises for full analyses within PRS/mu:

- H ZZ* 4

2-mu topologies: - H WW 2(=> - challenging for background rejection; - hot channel in the early days of LHC )

- Z ’ 2in the 1-2 TeV region (=> - challenging for pT resolution; - impact of alignment; - showering muons ....)

These will likely to go in the “Volume 1” of the Physics TDR(=> devoted to detector response, reconstruction of physics objects, calibrations, detector parameterization), under responsability of PRS groups=> benchmark for any “fast/parametrized” simulation/reconstruction

“Volume 2”: High-level analyses, like Higgs, Supersymmetry, Exotic physics, etc.=> “physics reach”of CMS , scan of models’ parameters space.... (responsability of new analyses groups)

“Data challenge” preparation

In Febr.’04, CMS will perform its first significant “Data Challenge” (DC04)i.e. large scale test of computing and analysis model:

Inject into the system a “sustained data-taking rate of 25 Hz at luminosity 2 1033 for 1 month” ( =>50 107 events), filter and analize them down to “physics plots”(+ calibration/alignment activity...)

prepare 50 M ev datasample (=> pre-data challange phase, MC production 10 times larger than for DAQ TDR; huge effort, GEANT4 training on big MC simulation (timing, crashes,...), Grid training, ect...): it will last 6 months, 2nd half of 2003

finalize HLT code for “Tier0” operations (50 M ev will be at HLT output)

use the 50 M ev for preliminary Physics TDR analysis (this will last presumably all 2004, after the DC04 itself)

see Silvia’s talk for PRS/mu details
