Ratio between the \pt-integrated yields of nuclei and protons as a function of multiplicity for (anti)deuterons (left) and (anti)helions (right). Measurements are performed in INEL $>$ 0 pp collisions at $\sqrt{s} = 5.02$ TeV, in high-multiplicity pp collisions at $\sqrt{s} = 13$ TeV , in INEL $>$ 0 pp collisions at $\sqrt{s} = 13$ TeV and at $\sqrt{s} = 7$ TeV , and in p--Pb collisions at $\snn = 5.02$ TeV . The statistical uncertainties are represented by vertical bars while the systematic uncertainties are represented by boxes. The two black lines are the theoretical predictions of the Thermal-FIST statistical model for two sizes of the correlation volume $V_\mathrm{C}$. For (anti)deuterons, the green band represents the expectation from a coalescence model . For (anti)helion, the green and blue lines represent the expectations from a two-body and three-body coalescence models
