Plan for Spin Plan:  Steve V. will discuss the deadline with DOE next week.  
I requested a later due date.  I told him that there was considerable 
progress today, gave him some of the progress (in notes below), 
and told him that the EIC and RHIC Users meetings would make it difficult to
complete this by the end of May.

I suggest that we hold to the schedule of having drafts based on our 
discussions today posted by Thursday, May 22, night.

I reported to him that certain plots are still missing.  They are:

--STAR figure showing charge separation for endcap Ws

--STAR figure for Ws with RHICBOS, using the set of pdfs we decided upon

--STAR figure for Ws vs. lepton rapidity

--PHENIX figure for 500 GeV pi0 A_LL (vs. x_T)

General: we had excellent discussions, particularly on making the case for 
the gluons and Ws.

(The transverse spin section was already ready.)  
See the sections below for these discussions.

In order of proposed spin plan:

Abstract-Here we will emphasize that we have exciting measurements to do, 
and the importance of running.

Executive summary-Yes, it is QCD and not QED. 
Gluon result is for a particular probed range.  
That range will be 0.02 to 0.3 (but check)-i.e. the range quoted 
by the experiments.
The very forward direct photon will be done with luminosity expected over 
the next 5 years.
Mid-rapidity direct photon (+ jet) will require about 300 pb^-1, 
and will be carried out as this integrated luminosity becomes available. 
We discussed a goal for this (it will always have less sensitivity than jet, 
pi0, etc.). Decided on roughly ±Delta G of about 0.05 (neg.) over the
measured range. This would correspond to about 1/5 of the GRSV std Delta G 
in this range.
Jim will look into the required L. 
Drop the "real".  Sensitivity to anti-quarks will be revisited
after realization that we do have significant sensitivity to Delta 
dbar with 300 pb^-1 (see W section).
In light of this, we will deemphasize the higher L remarks (1300 pb^-1), 
but include this point.

Introduction-Add direct photon (+ jet). 
Some discussion of including figures, but probably not.

Accelerator-The 1 month of AGS running ahead of RHIC is to improve 
the polarization for RHIC.
Include comment in executive summary. 
AGS polarization not known precisely-use * in table. 
Use 58% pol. in 2006 for RHIC.  More wording on spin flipper.

Note: we need to estimate vertex size, after 9 MHz and at 500 GeV (vs. 200).  
This should be in this section.

Polarimetry-Will be part of Accelerator section.  Include present AGS A_N calibration. Correct thickness of carbon ribbon.  Include upgrade plan and why.

Experiments-Match recorded L with other sections, Phil's numbers. 
Get vertex sizes using 9 MHz, and for 200 and 500 GeV, 
include in recorded/delivered ratio.  Include QA cuts in ratio.
Use "sampled". 
Table showing this ratio for Phenix, STAR, 200 GeV, 500 GeV (W).

Gluon-Propose to use these figures, in the following order: 
Fig. 1, 2, 4, new 3, gamma study.
This moves the dijet A_LL to right after the global fit to emphasize it. 
Describe it, emphasize its sensitivity-compare several points to the 
Delta G= 0.24 of GRSV std within measured range.
Note that each point maps out a narrow x range.  
The new Fig. 3 will be Phenix 500 pi0, using syst uncert. based on spin 
flipper operation, of 10^-4, and 300 pb^-1.  (This reaches x=.005.)
The gamma study figure is from Les, showing direct photon (inclusive) 
and background estimates.
This will reach about 2 x 10^-3 (check), and we should make an estimate 
of measurement sensitivity with N (50?) pb^-1.  
(Q: can we use the trick of internal photon conversion to get at
lower p_T direct photon for mid-rapidity?  
A: I think this has small S/B, but will check.)

W-Many interesting points. Decide to drop Fig. 1. 
Sensitivity to Delta dbar for Phenix forward production 
(about 5 sigma for 300 pb^-1). 
Star not so sensitive-has to do with S/B and the absorber in Phenix. 
Result is that we have significant measurements for both Delta dbar and
Delta ubar with 300 pb^-1.  Therefore don't emphasize 1300 pb^-1, 
but do state that additional L can significantly improve precision of this 
unique measurement.  dbar/ubar plot (unpol.) to show RHIC capability. 
Delta d/d-does it go from negative to positive (toward 1) for large x?
Looks like RHIC is very sensitive, at large rapidity. 
Can this be done by FMS and MPC?
In any case forward measurements will be very interesting. 
Still need to get argument for value of the large W parity-violating 
asymmetries in general in the valence region. 
Sasha notes that the central arm sensitivity looks smaller than earlier 
studies (for Phenix)-check.\
Look into including a central e^+ for Phenix and Star with uncertainties-
Fig. 3 suggests that this will have sensitivity to Delta dbar also. 
Include figure for STAR vs. y_lepton with uncertainties.
