  1. TOF QA report F. Bellini* on behalf of the TOF group *University di Bologna and INFN QA meeting, 11th July 2014

  2. F. Bellini, TOF QA report 26/06/14 Follow-up on the p PID issue in LHC11a_7TeV cpass1 • Reported at last QA meeting a tail for low-pT protons in LHC11a_7TeV cpass1 • Understood: https://alice.its.cern.ch/jira/browse/PWGPP-69 • problems to use the TPC PID in the tracking  all tracks considered as pionsunderestimation of low-pT p energy loss underestimation of texp  tail in t-texp and Nσ towards positive values • Notice that this affects all reconstructions, thus it is also a blocker for 2010 reprocessing • From technical point of view a fix exists but not yet committed (Ruben, private comm.) 145025 p 145079 p

  3. F. Bellini, TOF QA report 26/06/14 p-p, Pythia 8 minimum bias production - to calculate pi0 efficiencies in PHOS, EMCal and photon conversion analysis - anchored to LHC12[a-d], 8 TeV (RAW OCDB), ALIROOT-5456 LHC14e2a Average t-texp: -6 ns Average matching 72% • Ongoing • Checks on PID • Comparison with data

  4. F. Bellini, TOF QA report 26/06/14 p-p, Pythia 8 minimum bias production with added signals - pi0's, eta's, omega's - to calculate pi0 efficiencies in PHOS, EMCal and photon conversion analysis - anchored to LHC12[a-d], 8 TeV (RAW OCDB), ALIROOT-5456 LHC14e2b Average t-texp: -5 ns Average matching 76% • Ongoing • Checks on PID • Comparison with data

  5. F. Bellini, TOF QA report 26/06/14 LHC14e2c p-p, Phojet minimum bias production - to calculate pi0 efficiencies in PHOS, EMCal and photon conversion analysis - anchored to LHC12[a-d], 8 TeV (RAW OCDB), ALIROOT-5456 LHC14e2c Average t-texp: -7 ns Average matching 72% • Ongoing • Checks on PID • Comparison with data
