PARTICIPANTS: Yulia, Garth, Maranda, Richard, Rolf, Stephen, Tobias, Tanja, Patrick, Arun, Douglas, David R., Huey-Wen,


DETECTOR PLANNING

  • Overview validation studies of IP6 FF
  • Discussion of IP8 FF ongoing and planned studies
  • No difference for decay particles likely; maybe advantage of second set RP
  • Larger acceptance proton/neutron cone - magnet setup has larger bore in IP8 (4mr cone vs ~5mr cone)
  • Detector sizes
  • ZDC IP8 cone of accepted particles larger - note: if pT same then ZDC size larger
  • B0 configuration
  • Action items:
  • Continue IP6 FF validation
  • IP8 FF evaluation of MC samples
  • Check pT/t assumption for DVCS (where assume bore) and meson SF
  • Acceptance fractions


GLOBAL ANALYSIS

  • Work ongoing on lattice


MESON SIMULATIONS

  • Ongoing work on generators and Monte Carlo Samples


DISCUSSION OTHER

  • Quark-gluon sum rules and correlation with mass
  • Progress with the lattice - pion gluon content more difficult to calculate than nucleon - most of pion mass comes from momentum and calculation at higher momentum more challenging
  • Including resummation beyond NLO calculations has an impact on gluon contribution
  • Action item: consider possible small Pion-Kaon Workshop on topic of sum rules and mass correlation in ~6-8 months


NEXT MEETING: MONDAY 2 AUGUST 2021 AT 4:00PM ET
