General Meson SF Meeting Summary 7/12/21

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
