(Left) d/p ratio (Top) and \he/p ratio (Bottom) in pp, p--Pb, and Pb--Pb collisions~ as a function of the mean charged-particle pseudorapidity density. (Right) Coalescence parameters $B_2$ (Top) and $B_3$ (Bottom) as a function of the mean charged-particle pseudorapidity density for \pt/$A$~=~0.75~\gmom\ (0.73~\gmom) calculated using the average of particles and antiparticles. In all panels the expectations for the canonical statistical hadronisation model (SHM) evaluated with Thermal-FIST~ and coalescence approaches~ are shown. For the SHM, two different values of the correlation volume $V_{\rm c}$~ are displayed. The uncertainties of the coalescence calculations, which are due to the theoretical uncertainties on the emission source radius, are denoted as shaded bands.
