Action Items
- ChiPT calculation to one loop with Coulomb photon (Svetlana and Aleks)
- Follow-up contact with Marc to request paragraph (Rory)
- Provide relative yields for single pi0 production: Primakoff, NC, interference and IC. We can use these to scale 2pi0 yields (Ilya)
Tentative Agenda
- Announcements
- Action Items
- Feedback from collaboration review
- Theory update
- Experiment update
- Updates to collaboration draft
- Backgrounds to be simulated
- Background hits
- BGGEN (PYTHIA)
- eta production (Elton)
- Incoherent production (Elton)
- Npipi
- Table of cross sections (Rory and Ilya)
- Single pi0 estimates (Ilya)

- Experiment optimization
- Target position (Beni).. not yet
- Beam energy:
- Generate angular distributions for some other targets to compare to Pb
- Significance of experiment
- The expected uncertainties of the extracted gg->pi0pi0 cross section (Fig. 24 of proposal) need to be verified and studied more carefully
- Analysis of PRIMEX data
- Backgrounds to be simulated
- Other business
