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
