Hi Nihar,

Thanks for signing off! I have uploaded a newer version here: https://drupal.star.bnl.gov/STAR/system/files/DIS_Proceedings_063023.pdf

Best,

Hello Youqi,

Thank you for implementing my comments.

This camel case looks good to me: "SoftDrop" and "CollinearDrop"

L34:  where y1,2 and φ1,2 are respectively the rapidity…->  where y1,2
and φ1,2 are, respectively, the rapidity …

I sign off.

Cheers
