and pasted below.




Agenda

    * Hadron results
    * Analysis updates

Minutes

    * Attending: Diane, Craig, Carlos, Mike P., Dennis, Mukesh, Lei
    * Craig reports that after his talk at Hadron, Suh-Urk Chung suggested
that for a combined baryon-meson PWA we should look into using the
canonical formalism instead of the tensor or helicity formalism.
    * Craig is beginning to look into his start counter vertex time cut as
a cause to his yield problems. He's going to do an efficiency
calculation looking at p pi+ pi- exclusive events and come up with
numbers by paddle.
    * Diane reports that her talk went well. Much discussion ensues about
isovector and isoscalar interference, angular distributions of the a2,
and so on. Diane is going to look at the eta-pi+ system off the Delta0
and see what comes out.
    * Mukesh reports that his talk went well. There is some question about
the magnitude of background underneath the phi. Lei also suggests
using timing cuts instead of cuts on beta, since timing is not
momentum-dependent and beta is. Mukesh is also going to try looking in
the EC for two gammas to clean up the pi0 signal.
