Invariant-mass distributions of the \Dzero- and \Lc-hadron candidates and their charge conjugates produced in pp collisions at $\sqrt{s}=13 \TeV$ and reconstructed at midrapidity, shown in a selected \pt range. The values for the Gaussian mean $\mu$, width $\sigma$, and raw yield $S$ are reported. Top row: \DzerotoKpi meson candidates measured in the $2 < \pt < 4 \GeV/c$ interval. Middle row: \LctopKzeros baryon candidates measured in the $2 < \pt < 4 \GeV/c$ interval. Bottom row: \LctopKpi baryon candidates measured in the $2 < \pt < 4 \GeV/c$ interval. The corresponding BDT probability minimum threshold for the candidate selection is reported. The left (right) column corresponds to the prompt (non-prompt) \Dzero- and \Lc- hadron candidates enriched sample.
