Abstract A measurement of the production of prompt Λ c + baryons in Pb–Pb collisions at s NN = 5.02 TeV with the ALICE detector at the LHC is reported. The Λ c + and Λ ‾ c − were reconstructed at midrapidity ( | y | 0.5 ) via the hadronic decay channel Λ c + → p K S 0 (and charge conjugate) in the transverse momentum and centrality intervals 6 p T 12 GeV/c and 0–80%. The Λ c + / D 0 ratio, which is sensitive to the charm quark hadronisation mechanisms in the medium, is measured and found to be… CONTINUE READING
