  1. CHAMBER PRODUCTION AT CERN 904 RPC upgrade-meeting, 27.Nov.2013 Dong-hyun Kim on behalf of the cern-904 team Department of physics, sungkyunkwan university, korea

  2. Content • Status of Chamber • Plan

  3. 1. Status of Chamber • Built 3-RE4/3 Chambers • Ground cable and address finished • Ready to cosmic test

  4. 2. Plan • Dark current test for the RE4/3 Gaps • Build to 3 more RE4/3 Chamber • Check the new RE4/2 Gaps

  5. 3. Data Analysis • Study for Muon Efficiency at = 8TeV(Full pile-up events) • RD : /SingleMu/Run2012A-PromptReco-v1/RECO & /SingleMu/Run2012A-23May2012-v2/RECO • MC : /DYToMuMu_M-20_CT10_TuneZ2star_v2_8TeV-powheg-pythia6/Summer12_DR53X-PU_S10_START53_V7A-v1/AODSIM • JSON file : Cert_190456-203742_8TeV_22Jan2013ReReco_Collisions12_JSON.txt Cert_190782-190949_8TeV_May23ReReco_Collisions12_JSON_v2.tx • Use by Tag & Probe method • Running crab-job and then Get Data(RD & MC)

  6. 3. Data Analysis – Data type

  7. 3. Data Analysis – Data type • RAW : RAW event data contains detector data and trigger information. The largest contributor to the RAW event size of the order of 500 kB is the silicon strip detector. • RECO: The Reconstructed data (RECO) contain reconstructed physics quantities derived from RAW data. Detector calibration constants are applied and physics objects are identied. A RECO event is about 400 kBin size. • AOD: The Analysis Object Data (AOD) contains a small subset of the RECO data format, sucientfor 90% of all physics analyses. An AOD event is about 120 kBin size.

  8. 3. Data Analysis – Data type • GEN-SIM-RAW: The RAW data tier originating from Monte Carlo (MC) simulations with the Generator (GEN) information and the Simulation (SIM) information added. A GEN-SIM-RAW event is about 1000 kB in size. • GEN-SIM-RECO: Corresponds to RECO using GEN-SIM-RAW as input and contains small amounts of generator and simulation information. A GEN-SIM-RECO event is about 500 kBin size. • AODSIM: The AODSIM format contains a small subset of the GEN-SIM-RECO data format suffcientfor 90% of all analyses. An AODSIM event is about 140 kB in size.
