STAR Flow, Chirality and Vorticity PWG

["Feng, Yicheng" <feng216 AT purdue.edu>]

Hi FCV and CME-fg,

For our CME isobar baseline study, our short paper draft is now available on drupal:

https://drupal.star.bnl.gov/STAR/system/files/IsobarNfBkg_S_v7.pdf

and a new version of long paper draft can be found through

https://drupal.star.bnl.gov/STAR/system/files/IsobarNfBkg_L_v7.pdf

Now we use a new method to estimate the upper limit with constraint fcme>=0,

by following the reference [G. J. Feldman and R. D. Cousins, Phys. Rev. D57, 3873 (1998)].

The upper limits are nearly the same as before (only 0.2% lower),

but in this language, the confidence level is now 95% instead of 98%.

For Aihong's comment about backgrounds from rho meson spin alignment,

we added a statement in both short [98-102] and long drafts [180-183],

citing the reference and saying future assessments are needed for this effect.

More details can be found on the webpage:

Please let us know if you have any comments.

Sincerely,

Yicheng for the PAs

Hi FCV and CME-fg,

We had a PWGC preview for our CME isobar baseline study last month.

We updated the webpage and the long paper draft for this study,

which are available through the links below:

->Webpage: https://drupal.star.bnl.gov/STAR/blog/fengyich/Background-Baseline-CME-Isobar-Collisions-Webpage

->Long paper draft: https://drupal.star.bnl.gov/STAR/system/files/IsobarNfBkg_L_v5.pdf

If you have any questions/comments, please let us know.

Meanwhile, we are working on the short paper draft.

We will also upload that to drupal later and send an email to FCV and CME-fg lists.

Sincerely,

Yicheng for the PAs
