Production of (anti)(hyper)nuclei at the LHC with ALICE

The production mechanism of light (anti)nuclei and (anti)hypernuclei in hadron collisions is still under debate in high-energy physics. Two different classes of phenomenological models are used to describe the (hyper)nuclear production: the statistical hadronisation model and the coalescence model....

description The production mechanism of light (anti)nuclei and (anti)hypernuclei in hadron collisions is still under debate in high-energy physics. Two different classes of phenomenological models are used to describe the (hyper)nuclear production: the statistical hadronisation model and the coalescence model. Thanks to its excellent particle-identification capabilities, ALICE is the best experiment at the LHC for the measurement of (hyper)nuclei. During the LHC Run 1 and Run 2, ALICE has measured the production of (anti)(hyper)nuclei in pp, p--Pb and Pb--Pb collisions at different energies. For the first time it has been possible to measure hypertriton production in pp and p--Pb collisions. In the following, the latest results on the measured production of (anti)(hyper)nuclei is compared with the predictions of the coalescence model and of the statistical hadronisation model, in order to understand which of the two provides the best description.
