Detail description

 

Lc RAA in Pb-Pb collisions at sqrt(s_NN) = 5.02 TeV in 30-50% compared to prompt average non-strange D mesons, Ds and charged particles

The average of AdaBoost and XGBoost is used.

  • Data sample: LHC18q_pass1, LHC18r_pass1
  • List of runs: RunList_LHC18q_pass1_CentralBarrelTracking_hadronPID,  RunList_LHC18r_pass1_CentralBarrelTracking_hadronPID
  • Event cuts: |vtx_z| < 10 cm, trigger: kSemiCentral
  • pp reference from preliminary analysis with 2017 pp data at 5 TeV, but for the last point, which is extrapolated
  • Average D and Ds same as in https://alice-figure.web.cern.ch/node/15372
  • Charged particles from JHEP 1811 (2018) 13
