FAR FORWARD REGION EFFECTS (Yulia)

  • Working on document collecting FF effects for both IPs
  • crossing angles
  • vertex or momentum smearing


SOFTWARE (Dmitry)

  • joint effort to develop simulation for EIC (DD4HEP)
  • Anticipated to be released at BNL first - download and view data does not require an account though
  • To compare two beamlines when will the software be ready for it?
  • can be done in G4e presently with both IP6 and IP8 - need to add 10sigma for RP for IP8, need to take into account when calculating acceptances
  • with new software expect to have this ready in May
  • Beamlines also sent for implementation into Fun4All - Doug will check with Jin on the status
  • Smearing - Fast simulations tools
  • EICsmear (Kolja Kauder)
  • Delfes (Miguel Arratia)


GLOBAL ANALYSIS STUDIES (Patrick, Richard)

  • Ongoing: pion/kaon global impact studies, lattice QCD
  • Ongoing: model further development (splitting function, etc.), t-dependence/resolution


MESON FORM FACTORS (Garth)

  • Need to develop a generator - cross section parameterization
  • Study capabilities of the detector proposals for pion measurement
  • forward beamline
  • detection of forward going pion - t-resolution
  • Action item: implement generator into full detector simulation frameworks
  • Kaon form factor measurement
  • document lambda/sigma
  • Action item: investigate if one can separate lambda/sigma and actually make a measurement of kaon FF?


THEORY (Tobias, Patrick)

  • Ongoing:
  • thinking about calculation of mass distribution in pion in model
  • finished a paper on pion FF up to 100 GeV2 in fully relativistic model - see approach to valence at high momentum transfer
  • Calculating mass is difficult: calculation of mass in Minkowski very challenging


WORKSHOPS UPCOMING


JPHYSG ARTICLE ACCEPTANCE

  • Proofs should be forthcoming
  • Online publication link available
  • Action item: update arXiv paper


WIKI MESON SF (Arun)

  • Action items:
  • Update People section (names, email, ORCID)
  • Update Workshop section
  • Any other updates


NEXT MEETING: MONDAY MAY 3 AT 4:00PM ET

  • Simulations update
  • Workshop reviews
