  • Meeting Page (with agenda).
  • Review of last meeting minutes:
    • Collaboration Meeting Announcement: Sep. 21-22.
    • Analysis Review: nothing new.
    • Tulio's Presentation:

Tulio gave a presentation on his new and improved incoherent cross section of photoproduced π0. It turns out that

two different approaches, Tulio's and Sergey's, to the same physics give very similar results. The differences may

come from elementary procceses cross sections and implementation of Pauli blocking in those calculations. Tulio had

an elasticity cut of 0.9 in his results. Ashot pointed out that it would be good to see how results vary with the

elasticity cut. Tulio also stated that the effect of Pauli blocking in secondary scattering on the result is very

small. There's an urgent need to bring both calculations together on the same plot.

  • Analysis Review: nothing new.
  • Bases/Spring location: Pawel

Pawel put the code in the CVS, he will sent this to everyone. He showed his Yield Fits of Each T-counter comparison

plots. And he pointed a problem with the Monte Calo(MC) simulation, which comes from the 2 body and 3 body's

difference correspond to the normal and double hard compton. Eugene suggest that one can use the weights MC on the

face base generator.

  • Toward a final result: Rory et. al.

He can send his source to all in the maillist.

  • Next meeting chairperson: Mark, secretary: D. McNulty.
