Meeting Time: 11:00 a.m. JLab time

  1. To join via a Web Browser, go to the page [1] https://bluejeans.com/907185247.
  2. To join via Polycom room system go to the IP Address: 199.48.152.152 (bjn.vc) and enter the meeting ID: 907185247.
  3. To join via phone, use one of the following numbers and the Conference ID: 907185247.
    • US or Canada: +1 408 740 7256 or
    • US or Canada: +1 888 240 2560
  4. Upon connection all microphones are automatically muted. To unmute your mike on a Polycom or equivalent unit, enter *4. Unmuting on a computer is trivial as there is a microphone button than can be clicked.
  5. More information on connecting to bluejeans is available.

Goals for Calorimetry Group

  1. Determine preliminary photon reconstruction efficiencies as a function of E, phi and theta in data and simulation with a point-to-point precision of at least 5%.
  2. Measure systematics of pi0/eta mass calibration as a function of detector position to a precision of at least 5 MeV.
  3. Demonstrate agreement of photon reconstruction efficiency and resolution between data and simulation as a function of E, phi and theta to within 5%.

Action Items

  1. Short term
    1. Hadronic split off studies
    2. Covariance matrices for photons
    3. BCAL Wiki reorganization -> All
  2. Long term items
  3. Complete Calorimeter work packages

Minutes

Attending: Edmundo, Karthik, Varun, Zisis, Sean, Churamani, Colin, Tolga, Matt, Rebecca, Susan, Mark

  1. Announcements
    1. We will look at a new day/time for this meeting as some folks have time conflicts.
    2. MEDCON5 will continue at the lab throughout the long shutdown so at least until May.
  2. Action Items
    1. Short term: nothing to report
    2. Long term: data for Item 1 (FCAL LED) taken; Susan will look at it.
    3. Calorimetty Work Packages: these will discussed and the tables wil lbe updated.
      1. In Progress Table:
        • Row 2: Karthik will use a new bggen sample to check the z-dependence. Previously there was an error in the code and this will be looked at.
      2. Completed/Future Table:
  3. Run Update
