ePIC Jet Reco. Task Force
Discussion Notes
Derek Anderson
03.28.2023

Meeting start: 3:02 PM ET

Minimum Jet and Constituent pT
  - Xuan Li recommended sticking to 0.2 GeV/c
    and |eta| < 3.5 for tracks
  - |eta| < 3.5 corresponds to a minimum Jet
    energy of about
      Emin = 10 GeV * sin(2. * atan(exp(-3.5)))
      Emin = 0.6 GeV (roughly)
  - Brian suggests sticking to 1
    GeV for min. jet pT
    > Rationale: we don't need 1-track
      jets
  - Derek will push changes to default parameters
    after PR #488 gets merged
    > (should be this week)

Testing EICrecon jets
  - Derek thinking to prepare a plugin/macro to
    manually cluster jets later this week
    > Then will plot manual and EICrecon
      output on top of each other
    > Output to check:
      * Jet pT
      * Consituent momentum fraction
  - Brian already has code to do this, so
    he can modify that to work with
    EICrecon jet output
    > Will modify it to plot the manual
      and EICrecon output on top of
      each other
  - Brian and Derek will iterate more
    offline

Example Code Snippets
  - Code which tests EICrecon output will
    be a good example to include on
    wiki page
  - Derek asks if there's a place to store
    example code for ePIC
    > Kolja and Brian suggest reaching out
      to Markus

Wiki Page Reminder
  - Brian asks for elaboration on wiki
    page
  - Derek explains that wiki page will
    detail:
    * How to interact with EICrecon jet
      output
    * Example code Snippets
    * Links to meetings
    * And any other pertinent info

Upcoming Jet Meeting
  - Brian intends to hold a jet meetings
    in 1 or 2 weeks
    > We'll give summary of what the
      task force did
    > Kevin will give summary of epic-
      analysis
  - Brian points out that we should make
    sure task force meetings are 
    documented
    > Asks if there's a task force 
      category on the wiki
    > Derek says he doesn't think so,
      and suggests that the jet page 
      might be a better platform for
      linking to jet task force meetings

Meeting end: 3:22 (or so) pm ET
