Description

The formation of light nuclei and their antiparticles in high-energy hadronic and heavy-ion collisions can be described by two phenomenological models: the statistical hadronization model and the coalescence approach. The former assumes that light nuclei, as well as other hadrons, are produced thermally at the phase boundary in heavy-ion collisions, while the latter describes the light nuclei formation as the result of coalescence of nucleons which are close in the phase space.
\newline \indent
In this poster, results on the production yields of (anti-)$^{3}\mathrm{He}$ in p--Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV and elliptic flow measured in Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 2.76 and $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV for different centrality classes are presented.
\newline \indent
The attempt is to provide additional constraints to the coalescence model, thus contributing to an improved understanding of the process of formation of light nuclei in high-energy collisions. Integral part of this effort is the comparison of results in different collision systems such as p--Pb and Pb--Pb.
The measurement of the elliptic flow of (anti-)$^{3}\mathrm{He}$ in Pb--Pb collisions complements the picture obtained from the elliptic flow measurements of (anti-)protons and (anti-)deuterons.
