  In recent years, ALICE has extensively studied the production of light
(anti)(hyper)nuclei in different collision systems and center-of-mass energies.
Nevertheless, the production mechanisms of light (hyper)nuclei is still unclear
and under intense debate in the scientific community. Two classes of models are
typically used to describe nuclear production: the statistical hadronisation
model and the coalescence ones. In heavy-ion collisions, both models describe
well the production yields of light nuclei and their ratios to the yields of
hadrons, making it difficult to distinguish between the two. On the contrary,
small collision systems, such as pp and p-Pb collisions, are ideal to study the
(anti)(hyper)nuclei production mechanisms, thanks to the large separation
between the different predictions. In this paper, recent results on light
nuclei production measured with ALICE at the LHC in small collision systems are
discussed in the context of the nucleosynthesis models, allowing us to exclude
some configurations of the SHM and coalescence models in order to set tighter
constraints to the available theoretical predictions.
