ePIC Jet Reco. Task Force
Discussion Notes
Derek Anderson
02.28.2023

Meeting start: 3:05 PM ET

Apologies for the Zoom confusion!

Derek Updates
  - No movement on edm4hep front
     - Hopefully will be able to pull on this
       thread next week
  - However, using Reconstructed Particles
    class means we can get framework implemented
    now and worry about adding additional jet
    information later

Zhongling Updates
  - Framework of both truth (charged particle) and
    reco (charged track) are in place
  - Currently written assuming emd4eic::jet object,
    but will update code to write to RecoParticles
    soon

Dmitry Romanov requests that the group think of
  any issues/bugs/etc that are preventing or
  hampering our work and provide it to him
  - His task force is working to fix these
    issues before the next simulation campaign
  - Derek: to my mind, there are no bugs
    impeding our work
    - We'll aim to compile/test jet framework
      by end of the week
    - After that we should have a better idea
      if there are any issues

Derek: I'd like to revist what our goals for
  the sim campaign and discuss the timeline
  for their completion
  - They are:
    (1) Get framework implemented for charged
        particle + charged track jet tracks
    (2) Calculate JES/R with those
  - Brian points out that another goal is
    (3) Work out rough idea of jet parameters
  - Strawman timeline:
    (i)   Switch draft PR to actual PR for
          factories by end of this week
    (ii)  Discuss jet parameters at this
          meeting next week
    (iii) Push agreed on changes by end of
          next week
  - So we should finish by 2nd week
    of March!

Derek: given that we should have time before
  the campaign starts, are there any other
  items we'd like to look at?
  - Brian: we could try implementing a
    calo jet factory as a stretch goal
    - They'll be rough (clusters aren't 
      in the best shape now, we won't 
      have time to work out how to properly
      combine the calos, etc.)
    - But we can at least get the
      framework there

Takeway: timeline for finishing task
  (1) Finish implementing charged particle/
      track factories this week and open
      PR
  (2) Discuss and settle on jet parameters
      to use for sim campaign next week
  (3) Time permitting, add factory for
      calo jets in 2nd half of March

Meeting end: 3:24 pm ET
