Hi, folks

Thanks all for a great meeting.

Here is a brief summary and todo list
1. Overall, g11 result is in good agreement with eg3 proton result for
differential and total cross section.
2. cut or not cut away Phi have very small effect for both eg3 and g11,
while g11 only has pK+(K-) topology with access to Phi kinematicaly.
3. for eg3, check totla cross section by only sum up differential cross
section instead of extrapolating and fitting
4. for eg3, check fitting models (relativistic breit-wigner etc),
particular at higher t.
5. for eg3, check simulation condition and study acceptance, particular
at small t
6. for g11 and eg3, check low energy total cross section.
7. for g11 and eg3, check decay angle distribution at different
t-channel K angle.
8. communicate with ODU about their opinion on Phi. ( I will write to Gagik)
9. see what's update from g10
10. communication with theorist about the calculation. ( Raffaella,
would you like to send the cross section result to Nam now or later? )
11. finishing up analysis note and start the review and publication in
same pace.

Please let me know what I missed.

PS, in Nam's latest paper (Phys. Rev. C, 81(5):055206, May 2010), the
decay angle distribution has some mistakes on axis labels, the
attachment is the corrected version from him.

Let's find a time and talk again during CLAS meeting in two weeks

Thanks

Zhiwen
