Dear Convenors,

We would like to request PWGC preview for the ‘Light Nuclei Femtoscopy at 3 GeV’ paper.

The detailed information can be found from the following links:

-> Paper proposal in PWG: https://drupal.star.bnl.gov/STAR/blog/kmi/20221222PaperProposalLightNucleiCF3GeV

-> Webpage: https://www.star.bnl.gov/protected/bulkcorr/kmi/paper/LightNuclei/LightNuclei_CF.html

Please kindly let us know if any other information is needed. Thank you.

Best regards,

Ke

Dear Convenors and all,

Last month on 22th I gave a paper proposal talk about ‘Light Nuclei Femtoscopy at 3 GeV’. I’d like to thank you for all the insightful discussion and comments.

Here we provide a supplement slide to the comments. The slide can be found through:

Main questions:

(1) Is there any centrality dependence about the extracted f_0 and d_0?

The results on the centrality dependent fits are shown in slides 10 and 14 for p-d and d-d CFs, respectively. 
As one can see, for p-d CFs (slide 10) , the results are consistent within 3-sigma. For d-d CFs, there is no centrality dependence for d0, but seems a slight centrality dependence for f0 (slide 14) between the most peripheral (40-60%) and mid-central collisions (0-10% and 10-20%).

(2) How the systematic errors of R_G, f_0 and d_0 calculated?

We change the different fitting range, and also change simultaneously fit into individual fit. The differences (1sigma) are counted as the systematics. The formation is listed in slide11. Tables are provided according to Hanna’s suggestion.

Any comments or suggestions are highly welcome.

Thank you.

Best regards,

Ke
