Notes by Elton.

== Announcements==
# Last weeks meeting was short due to various conflicting schedules.

== Draft of Phi-- Paper (Hovanes) ==
# Elton gave feedback to Hovanes. The draft is converging. Elton placed
the script for producting the trigger efficiency plot under cvs so that
the figure could be easily updated.
# Stepan requested a pdf version of the paper to read this week.
# Hovanes plans to implement feedback this weekend. At that point, it
should be in fairly good shape.

== Analysis note for Lambda(1520) (Zhiwen) ==
# Analysis note will be posted soon for reference.
# Zhiwen met with Rafaella and Alex to compare results at the level of
differential t' distributions, total cross sections and t-slopes
# Topology is gp->pK+K- with pK- resonating in a Lambda(1520).
# The results are mostly comparable, although there are some systematics
that need investigating
# Stepan: check distributions with high missing momenta, which includes
the Fermi tail, but also considerable re-scattering effects.
# Hovanes: Laget would be very interested in the missing mass dependence
of the reaction
# Stepan: for the g10 data set, fairly advanced analysis of Lambda on the
proton (McKinnon) and on the neutron (Nathan) have been done, but lack
finalization
# Elton: Check kinematics, especially at low t' to make sure that
kinematic bins (without complete coverage) are properly interpreted. Elton
will send link to "bin centering" corrections clas note.


== Next Meeting Mov 4, 8:00 am ==
# Phi-- Draft of paper (Hovanes)
# Theta+ update (Zhiwen)
