Agenda

Durga:
  • Estimate of the systematic error associated with rate-dependence in TOF?
  • Does TOF calibration vs path length help at all?
Chris Hunt and Rogers Scott and Tanaz:
  • Discussion of muon shoulder; radial cuts; etc
Celeste:
  • Any results for likelihood-based PID?
Jan, Yingpeng and Rogers:
  • What is the source of disagreement between TOF and tracker?
    • What is the material budget between TOF and tracker? Is it correct? (See Francois also)
    • What is the solenoid alignment like
Joe and Victoria:
  • Are the OPERA model and Hall probes consistent? How big are the inconsistencies?
  • Continue trying to untangle the field mapping data for SSU
Francois:
  • Can the agreement between MC and data be improved? Dipole fiddling?
    • At what statistical significance do MC and data disagree?
    • What are the systematic errors (e.g. from quad/dipole/solenoid settings, incorrect material model etc)?
Victoria:
  • Decoupled/2D emittance calculation?

TOF
  • Issue with MC
    • Rayner calibration was not working with MC; taking calibrations from data and plugging them into MC was not okay
    • Got good results by doing calibration using TOF0
    • Fit fails on TOF1
  • Offset of 60-100 ps - no progress
    • Speed of light offset did not give the expected correction; needs digging
