Minutes

Attending: Andrew, Beni, David H., David L., Elton, Nikhil, Rory, Sergey, Simon

  1. Previous CPP meeting: Nov 3, 2021
  2. Announcements
  3. Action Items
  4. Keynote Speaker: Systematic Study of Polarization Determination with BH (Andrew)
    • Andrew presented a plan to study systematic uncertainties in the determination of the polarization using BH electron pairs
    1. Andrew: Possibly choose the range of m_pipi mass over which different polarization orientations agree and compare to full analysis.
      • Can also compare the results of individual polarization orientations with sum of all (where acceptances seem to cancel).
    2. Use different AI tools and compare with current analysis
      • David: May depend on accuracy of model.
      • Another option is to take different sample sets (e.g. 80% for training and 20% for validation) and check differences of output
    3. Elton: Vary cuts used in analysis and check how sensitive the polarization extraction is to a particular cut
  5. Software/Calibration for CPP (David, Alex and Sean)
  6. AI for Experimental Controls testing during CPP
  7. DAQ Configuration (Sergey)
    • What specific crate and roc to use?
    • We probably wish to leave the CDC crate on the upstream platform and use a new (spare) crate.
    • Sergey suggests to not use the cdc roc, which has a unique name. Elton: We should implement a configuration that is easy for the DAQ. Sergey will look for the roc that was used during the FMWPC test in the hall. If not he will configure a new one.
