General Meson SF Meeting Summary 9/16/21

PARTICIPANTS: Ali, David, Garth, Richard, Rolf, Yulia, Tanja, Douglas

MESON SF SIMULATIONS (Richard)

• ZDC distribution comparison from Yellow Report (Yulia, G4E) vs. Fun4All implementation with all latest updates

• distributions look very similar
• outlier is 5 on 41, does not scale with proton energy as expected
• detection efficiency nearly 100% for neutron

• next: IP8 studies

• Action items:

• check with Bill on status IP8 simulation including far forward beamline
• Fix 5 on 41 setting, then could make comparison with YR

PION FORM FACTOR (Stephen, Garth)

• First results distributions and rates estimations at different Q2 ranges

• What needs to be done to make plots for IP8 configurations?

• in principle nothing stops from WG - simulation group needs

• Action items:

• compare different IPs - to what extent does it impact t-distribution
• different energies

THEORY (David, Patrick)

• Studies of impact lattice plus global fitting on PDFs ongoing

KAON FORM FACTOR (Ali)

• Working on analysis, and in particular for Lambda decay and ZDC distributions

• Action items:

• generate t-distribution to show difference between pion and kaon reactions --> sets constraints on far forward beam line
• detection efficiency ZDC
• analyze KSigma channel
• IP comparison - to what extent impact Lambda decay

NEXT MEETING: THURSDAY 30 SEPTEMBER AT 5:00PM ET
