Invariant-mass (M) distributions of D0->Kpi candidates and charge
conjugates in different pT and multiplicity intervals evaluated at midrapidity. The blue solid lines show the total
fit functions and the red dashed lines are the combinatorial-background terms. The
values of the mean (μ) and the width (σ ) of the signal peak are reported together with the signal counts (S) and the
signal-to-background ratio (S/B) in the mass interval (μ 3σ , μ + 3σ ). Only the statistical uncertainties from the
fit are reported.
