SPIN PWG presentation (11/ 6/ 17) : requesting convener preview : Slides

Comments / Questions

Carl :

1) EMC systematics theory method - Why W- values are factor two smaller than W+? . I would expect it to be otherwise.

2) What about AL (Z) I hope it will be included.

3) Suggestion to include only data points of run 12 and run 13 in figure 4 and remove everything else. And add another column in the proposed table to put combined AL values through run 11 to run 13.

Oleg:

1) What are the systematic for W ALL?
2) Did any study done to stay away from BEMC margins?

Scott:

1) Suggestions to make 2 legends for W+ and W- for figure 5. Follow up by carl several other suggestions to use different colors for W+ and W- and also for text to make it clear and easily separate W+ and W-

Jinlong : Theory_curves Updates : Slides

Devika : Theory_curves Updates: Slides

Discussion :
* Need to decide on Final cuts sets (Weather to use New cuts or Preliminary cuts)
* Finalize theory curves

Jinlong : W AL Theory curves - Slides

Discussion / Comments:

*We need to Include BS model curve which is based on statistical method
*What Unpolarized is used for NNPDFpol1.1 , NNPDF2.3 ? (Need to make this clear)
*MSTW08 for DSSV14 and MSRT for DSSV08, Not big difference for different unpol PDFs
*Make it clear why use a particular unpolarized set (Based on their global analysis)

W meeting - 06/28/17:

Jinlong : Horizontal Error Bars - https://drupal.star.bnl.gov/STAR/system/files/status_discussion_20170628.pdf

Devika : Embedding QA - https://drupal.star.bnl.gov/STAR/blog/devika/run-13-w-analysis-final-results-embedding-qa

Discussion / Conclusions:

* Remove Horizontal Error bars for run 13 leave them for run 12.
* Shift Run 12 points by a small amount (0.5 units)- Little overlap in the points is OK.
* Embedding - Perhaps try with a larger sample (more study ?)
* BEMC calibration systematics : ?
* Include RHICBOS

Paper Proposal to PWG - 06/26/17:

Comments / Questions from PWG:

Scott :

1) What is the conclusion of ALL?

**If a plot is not showing a sentence about ALL in the summary/conclusion would be good.

Oleg :

1) What is the Eta overlap for BEMC and EEMC? (Physics Eta vs Lab Eta)

Clarify this in the text to avoid confusions.

2) Horizontal Error bars on the results plots? How to interpret?

Renee:

Will ask later.

Elke:

1) What about Z boson AL ? Is it going to include ?

2) Is the Impact of data on PDFs going to include? (We don’t need NNPDF necessary, we can also do ourselves. GEM collaboration PDFS ??)

Scott and ALL,

**Another presentation to PWG before go to the PWGC would be good. Once pending items are completed!
