ePIC Jet Reco. Task Force
Discussion Notes
Derek Anderson
03.21.2023

Meeting start: 3:02 PM ET

Updates From Kevin:
  - Pushed several large changes to epic-analysis
    which should be merged soon (PR #242)
  - Summary of changes:
    > Created a 'KinematicsJet' class which
      stores kinematic information of jets
    > Consolidated all methods from the
      general kinematics class into 
      relevant locations
    > Added pointers to KinematicsJet
      objects in main analysis classes
    > Goal is to have a dedicated kinematics
      class for each type of analysis (SIDIS,
      DIS, Jets, etc.)
  - Brian asks if input to epic-analysis will
    be similar to the old delphes-analysis 
    framework (i.e. will epic-analysis read
    in ePIC simulation output?)
    > Kevin confirms this
  - Derek asks if using the ReconstructedParticles
    class in EICrecon to store jet info will
    work with epic-analysis?
    > Brian responds that it should, pointing
      out that Chris has consciously built
      PODIO integration into the framework

Derek asks Zhongling about status of storing
jet constituents in ReconstructedPartice
containers
  - Zhongling points out that this was done last
    week and ir ready for review in PR #488
    > Derek will bring up that PR #488 is ready to
      review and merge during S&C meeting on March
      22nd
  - Zhongling points out that we should document
    this behavior
    > Brian agrees
    > Derek offers to help with documentation

FastJet Contribution Discussion
  - Derek asks group what FastJet contributions
    we would like to include in eic-shell to
    pass onto Wouter
    > Brian asks if user picks what FastJet contribs
      to install or if they install the whole
      library at once
    > Kolja points out that you install the whole
      library at once
  - Kolja clarifies that Wouter wants to know what
    FastJet Contribs users are interested in/use 
    so that he knows how often to check for updates
  - Group discusses and comes to the consensus
    that we should
    (1) install the most current (ca. March 23rd,
        2023) version of the whole library, and
    (2) just go from there.
        > If users request more up-to-date versions
          of something, we can relay that to Wouter

Open Discussion
  - Brian asks if there's any word on the anticipated
    start date of the simulation campaign. (Is it
    still the end of March?)
    > Derek states that he hasn't heard otherwise...

Meeting end: 3:29 pm ET
