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, assigned man power, status (clean it up , structure it )

1. STAR
   1. BTOW
      1. absolute calibration accuracy
         
   2. TPC
      
   3. Trigger

1. RHIC

2. relative spin dependent lumi (based on BHT3 in muDst)
3. assemble .tex files with outline of the paper
4. list of cross checks on the data
5. absolute cross section from BHT3
6. theory calculation for our bins, vary input PDFs, average sign
7. spin bits or bXing --> spin pattern mapping

• Vet MC/Data
• Background model for what's under the Jacobian peak
• Relative Lumi QA
• CNI Polarization and Polarization QA
• effect of non longitudinal beam polarization
• Vernier scan cross section
  • uncertainties
• PPV vetting/debugging
  • Jan: do not care if it better than 3 cm accurate
• PPV acceptance correction when triggered on L2W trigger
• BTOW relative gains
• BTOW absolute gains + uncertainty
• Energy resolution of 2x2/3x3 clustering
• TPC pointing accuracy
• W-Algo acceptance corrections (will need input from TPC pointing accuracy)
