Left: extracted $\Re f_0$ and $\Im f_0$ for the $\Lambda K^+$ (red diamonds) and $\Lambda K^-$ (red dots) interaction in pp collisions, compared to Pb-Pb results (blue)  and available models (orange , magenta , green , and light cyan ). Statistical (bars) and systematic (boxes) uncertainties are shown. Right: extracted effective range $d_0$ obtained in this work (red) and in Pb-Pb collisions (blue) .
