General MWG Meeting Summary 3/30/20

SIMULATION UPDATES

• Richard's comparison of G4 and Fast MC

• Everything looks consistent - looked at distributions of angle vs. momentum for scattered electron, meson, and forward baryon
• Effect of the crossing angle (25 mrs ~1.4 degrees) can be observed in forward neutron distributions - independent of ion beam energy these peak at ~1.4 degrees, become more narrow as the energy increases
• Richard's slides

• Discussion of any remaining technical details for pion SF, pion FF simulations

• main goal: want to run event samples through detector + smearing
• EIC smearing software is being updated to include forward detection

• Virtual detectors: for April 13 Working meeting would like to evaluate virtual detectors and correlations

• Discussion of event generators

• currently support LUND file input into detector simulation
• event generators could be stored with the software framework - the idea is to have the generator that was used to generate specific plots available in the same place

ACTION ITEMS

• List of items for the 13 April Working meeting

• Work out technical details for pion SF, pion FF simulations, e.g. include realistic beam energy smearing etc.
• Neutron detection efficiency
• Hyperon (Lambda) decay and reconstruction
• Virtual detectors

• Circulate an agenda for the 13 April Working meeting

• General structure: common meeting interleaved with working meetings on simulations

• Phone meeting in week April 6 goals:

• discussions including theory, lattice, global fits plans for upcoming Workshops
• agenda for the June CFNS Workshop on meson structure
