STAR HardProbes PWG

[Youqi Song <youqi.song AT yale.edu>]

Hi Yi, all,

Since the PWG has reached the decision to treat pi0s, eta and sigma0 as stable particles at the generator level for correction purposes in ongoing jet substructure analyses, we would like to request a reproduction of Run 12 pp 200 GeV embedding. We would like most of the settings to be the same as in the embedding request from Dmitry with the following changes:

- include pi0, eta and sigma0 into the list of particles not to be decayed by PYTHIA;

- have the issues listed in section 5 errata of the embedding request from Dmitry fixed, if possible. 

Please find our embedding request attached (also uploaded to drupal), similar to Dmitry's request, but with the addition of particles to be kept stable at the PYTHIA generator level, which is marked in red on pg. 3.

For the record, here are some of the relevant slides we have prepared/presented:

intent for embedding reproduction: https://drupal.star.bnl.gov/STAR/system/files/embedding_meeting_120523.pdf

comparison of jet substructure distributions with and without the decays: https://drupal.star.bnl.gov/STAR/system/files/star_collab_meeting_101723.pdf

QA for the most recent embedding: https://drupal.star.bnl.gov/STAR/system/files/Run%2012%20pp%20new%20embedding%20QA.pdf

Please let us know if you have any questions or need any additional information. Thank you!

Best,

Youqi
