A comparison between the Lc / D0 ratio as a function of pT in the range 2-24 GeV/c between the measurements in 0-10% and 30-50% central Pb-Pb collisions at sqrt(s_NN) = 5.02 TeV (2018 data sample).

Detail description

 

A comparison between the Lc / D0 ratio as a function of pT in the range 2-24 GeV/c between the measurements in 0-10% and 30-50% central Pb-Pb collisions at sqrt(s_NN) = 5.02 TeV (2018 data sample). The Lc points are averaged over the AdaBoost (TMVA) and XGBoost (MLHEP) methods. The D0 measurement is performed in the same data sample and rebinned to the same pT binning.

  • 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: kCentral or kSemiCentral
  • pp reference from preliminary analysis with 2017 pp data at 5 TeV, but for the last point, which is extrapolated (needed for f_prompt calculation.
