Investigating light nuclei production in heavy-ion collisions using flow measurements in ALICE

<!--HTML--><div class="page"> <div class="layoutArea"> <div class="column"> <p><span>The production mechanisms of light (anti)nuclei in ultrarelativistic heavy-ion collisions are still not understood and currently under intense debate in the scientific community. Light (anti)nuclei have binding energies that are typically much less than the temperature at which they are produced (T </span><span>≈ </span><span>156 MeV), and mysteriously survive under the extreme conditions of the hadron gas phase. The latter occurs after the phase transition from a deconfined system of quarks and gluons and is characterized by a high particle density and high rate of hadron interactions. </span></p> <p><span>Azimuthal anisotropies of light (anti)nuclei production with respect to the symmetry plane of the collision are key observables to study the dynamics of interactions in the hadron gas phase and to shed light on the production mechanism of these fragile objects. In this seminar, the first measurements of (anti)</span><span>3</span><span>He elliptic flow and (anti)deuteron elliptic and tri- angular flow in Pb–Pb collisions at 5.02 TeV will be presented. The interpretation of these results will be discussed in the context of state-of-the-art theoretical models. Future perspectives for (anti)nuclei flow measurements in Run 3 will be presented and the motivation to extend these measurements to small collision systems will also be discussed.</span></p> <p>Passcode: 139358</p> </div> </div> </div>
