The purpose of this meeting is to examine in detail the requirements of the Eight+ facility for doing physics at 8, 10 and 12 GeV photon energies. In this study, we need to focus on early physics, as well as the ultimate physics we want to accomplish. There are several important questions which need to be examined for each possible reaction.

It will also be important to run some spin-parity analysis ala-e852 to try and estimate where our our problems are going to be. There are a couple of clear issues that have come up -- how do we handle the possibility of resonances in the recoil baryon? What most seriously cuts into our angular distributions. Based on Crystal Barrel analysis where the crossing bands in the Dalitz plot remove the ambiguities encountered in E852, we may really want to try to include these baryons in the analysis -- even though no one knows how to do it in a reasonable fashion?

Finally, Paul Eugenio (telephone 412-268-6949, email:eugenio$#064;ernest0phys0cmu0edu) has written a simple toy Monte Carlo. It is still in development, but I am able to use it to produce files. It is steerable via a simple card file, and throws simple Breit-Wigner's with decays (into both stable and unstable daughters). At the moment, it does not have angular distributions. A copy of the code, Makefiles and input cards is available. The code produces an ascii output file. I have pasted together a simple fortran code to read in the ascii file, and create paw ntuples. This file is simply compiled and then linked to packlib. These are all fairly rudimentary, but should provide a starting point.
