U.Gasparini10/04/033 CCS schedule (detailed ) CMSIM OSCAR development of first “full off-line” analyses (i.e. beyond HLT) on predefined benchmark channels

U.Gasparini10/04/034 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 MB2.2.4 (courtesy of M.Benettoni)

U.Gasparini10/04/035 Post DAQ TDR activity -develop first full off-line analyses down to O( ) 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  2  2 (see M.Zanetti’s talk)

6 Post DAQ TDR activity Current 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 ’  2  in the 1-2 TeV region (=> - challenging for p T 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) next slide...

U.Gasparini10/04/037 SM Higgs searches Compare Tevatron: H  WW  2l  H  ZZ*  4l Run II A Luminosity They are here 140 GeV

U.Gasparini10/04/038 “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 for 1 month” ( => 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
