Two studied bins in rapidity y and transverse momentum pT of the \({K}_{S}^{0}\) are presented, left: y ∈ ( −1.0, −0.5), pT ∈ (1.2, 1.5) GeV/c, right: y ∈ (0.5, 1.0), pT ∈ (1.2, 1.5) GeV/c. Only statistical uncertainties are presented. The bottom panels show the difference between the experimental data and the fitted (Signal+Background) distribution, divided by the experimental uncertainty.
