General MWG Meeting Summary 1/24/20

DISCUSSION MATERIAL

Meson Structure WG for EIC YR

MESON STRUCTURE WG GENERAL GOALS

• Integrate into YR - contribute to this report

• Science Motivation - mass mechanism in pion/kaon as way to understand QCD, puzzles about gluon content, large x

• Check if can adequately do the meson structure physics with the EIC at BNL

• drives the detector design, e.g. what resolution needed, etc.

ACTIVITIES AND TIMELINE

• Experimentalist goal for May 22-24 EICUG Workshop: concretely say what is needed to do meson structure science

• redo (some of) the simulations with realistic accelerator and detector setup, and in particular check forward tracking scheme for Sullivan process, calorimeter requirements, etc.
• have done projections for Fpi, not yet investigated FKaon - also have not yet made projections for constraining gluons in pion/kaon

• Theorist (lattice) goal: large-x structure function

• time distributions
• Kaon calculations may be possible by June CFNS Workshop

• General Goals of the EICUG Workshops:

• Temple U (March 19-22): initiate detector complementarity study based on detector technologies
• Pavia U. (May 22-24)
• CUA (September)

• Future pion/kaon structure workshops

• ECT* 2021 - approved workshop (Daniele, Craig, Christian, Tanja)
• Plan to (re)submit an INT program proposal (Craig, David, Tanja)
