Draft: Hlt2 and Sprucing strategy for PbPb and PbSMOG2 2024

Samuel Belin requested to merge sbelin_PbPb_2024 into 2024-patches

MR to prepare the 2024 heavy ion data taking

For PbPb:

  • Keep hadronic PbPb + UPC lines as they were in 2023
  • Add jpsi/upsi line to get ready to use data
  • Prepare Hlt2 Monitoring (Ks L0)

For PbSMOG2:

  • With the addition of the ghost reduction thks to UT we can have a proper hlt2 strategy
  • The physics case almost identical to the pSMOG2 -> tune the lines from pSMOG2

To do:

  • Finish tuning the PBSMOG2 rate
  • add a PbPb tag for the pSMOG builder

Note: From first tests the average event size seems much more bigger than in 2023 (~1Mb compared to 130Kb in 2023). Might be due to Upstream and downstream tracks plus UT rawbank, has to be investigated and possibly write a new persistreco version.
