Lc / D0 ratio for different pT bins versus Nch/deta SPD ntracklet multiplicity classes: [1-9], [10-29], [30-60], [60-99] in pp 13 TeV, MB in pPb 5.02 TeV (2011.06078, 2011.06079), and 0-10% and 30-50% Pb-Pb 5.02 TeV (2018, preliminary).

Detail description

Lc / D0 ratio for different pT bins versus Nch/deta SPD ntracklet multiplicity classes: [1-9], [10-29], [30-60], [60-99] in pp 13 TeV, MB in pPb 5.02 TeV, and 0-10% and 30-50% Pb-Pb 5.02 TeV (2018). The analysed decay chain is Lc to pKpi for pp (MB), and an average over Lc to pKpi and Lc to pK0s for p-Pb and pp (HM) and Lc to pK0s for Pb-Pb. The p-Pb points are from 2011.06078+2011.06079 and merged to have the same binning at low pT, the Pb-Pb points are the preliminary ones at October 2019.
