Run 9 data publication strategy

Ordered list of goals leading to publication of W (and Z?) STAR data from pp500 STAR data from Run 9

Goal 1 Release the plot with Jacobian peak for Ws with yield on the Y-axis.

Details

• use 'best' 80% of STAR data
• xxxx

Goal 2 PRL paper #1

Title: First Observation of W boson production in polarized proton-proton collisions at sqrt(s)=500 GeV

Abstract:

• data shown: W x-section, A_L(W) combined for W+ & W-
• emphasis on observation of parity violating SSA in a collider
• describe experiment, analysis technique

List of figures:

1. Lego-plot with BTOW response from single W event
2. M-C to data comparison , 2-4 small panels
3. Jacobian peak showing
4. AL W+ & W- combined, 1 or 2 bins in ET with overlay of theory curves

Decisions:

1. we aim to circulate draft in spin PWG ASAP
2. we will use only BTOW, TPC, perhaps ETOW for away ET veto. BSMD will not be used.
3. no reason to request another production for this publication
4. Z's (if confirmed) will not be included in this paper. BTW, the same holds if Zs are not confirmed.

List of task, TBD: assigned man power, status

1. STAR
   1. BTOW
      1. absolute calibration accuracy
      2. relative gains
      3. BTOW absolute gains + uncertainty
      4. Evaluate improvement in ET of 2x2/3x3 clustering vs. QCD-background rejection
         
   2. TPC
      1. identify reason for inefficiency at eta~0, no replay of BFC
      2. compare TPC track position accuracy data/MC
         
   3. Vertex finder (PPV) vetting/debugging
      1. Jan: is 3cm accuracy enough for x-section paper?
      2. acceptance correction when triggered on L2W trigger
         
   4. Trigger
      1. relative spin dependent lumi (based on BHT3 in muDst), QA
      2. absolute cross section from BHT3
      3. spin bits or bXing --> spin pattern mapping
         
   5. VPD local polarimeter
      1. magnitude non longitudinal beam polarization
         
   6. Vernier scan (abs lumi @ STAR)
      1. determine BHT3 cross section
      2. estimate error, beam background contribution to BHT3 X-section
      3. vet BHT3 & BBC abs X-section used
         
   7. Simulations
      1. Vet MC/Data
         
   8. W-algo evaluation
      1. Background model for what's under the Jacobian peak
      2. acceptance corrections (will need input from TPC track position accuracy)
         
2. RHIC Polarization
   1. pol patter per fill
   2. CNI Polarization, QA
      
3. Theory
   1. calculation for our bins
   2. vary input PDFs, average sign
   3. effect of non longitudinal beam polarization
      
4. Organization
   1. refine this list
   2. assemble .tex files with outline of the paper
