Measured correlation function of \paL (left) and \LaL (right) pairs for two representative \mt bins. Statistical (bars) and systematic (boxes) uncertainties are shown separately. Results using the \Ledn formula with \PbPb scattering parameters~ are shown in light green. Orange bands are the results with \effran and \Imscatt as free parameters. In grey the corresponding $C_{\rm{background}}(\ks)$, multiplied by the normalization constant $N_D$, is shown. The reported average $\chi^2/\rm NDF$ is evaluated in the \ks interval $[0,400]$ \MeVc and it includes correlations between the data points Lower panel: same as in Fig.~\ref{fig:pApCFs}.
