New webpage for the paper is coming.

PWGC proposal done on Nov. 18, 2014, need to repeat previews

Update 7/11/2016: The main remaining analysis items are, as of July 2016:

2 use of ZDC-SMD to extend V0 and phi results to 62.4 and 200 GeV (200 GeV 

done; 62.4 nearly finished)

3 interpretation of net-/\ and net-kaon (still evolving & still checking va

rious ideas, but we plan to wrap-up soon)

- SINAP Papers

http://www.star.bnl.gov/HyperNews-star/protected/get/bulkcorr/2886/2.html

1. Proton-Omega correlations (Neha Shah)

2. Proton-Xi correlations (Chi Zhang)

For Proton-Omega, we need to work on pair purity, momentum smearing

corrections to the correlation function and systematic errors.

Working on QA for the other analyses. Will need embedding for

all three analyses.

Paper proposal or Proton-Omega, 6 months. Others are 6-12 months.

and this analysis adds centrality dependence. May be included

into joint paper for charged particle spectra and flow in 14.5 GeV.

embedding for kaons for p+p.

for like-sign, for unlike sign, model and other theoretical

predictions for CF in region of resonance, more detailed study

of CF in region of resonance, 3D, systematic errors

now back at LBL as a postdoc and working on the systematic

errors. We have not yet started to write.

Spin

From spin [...] the following analysis might request GPC soon:

 

very likely:

-FMS pi0 A_LL

maybe:

-Run11 IFF (not clear since analyzer moved to PHENIX)

-Run9 jet x-section (imho doubtful but analyzers proclaim their intent)

 

There are also the W A_L and W x-section ratio where we plan to have

the run13 preliminary in the next three months. I would expect that

the papers will follow very shortly afterwards.
