Abstract
The production mechanism of (anti)nuclei in ultrarelativistic hadronic collisions is under debate in the scientific community. Two successful models used for the description of the experimental measurements are the statistical hadronization model and the coalescence approach. In the latter, multibaryon states are assumed to be formed by the coalescence of baryons that are close in phase-space at kinetic freeze-out. Given the collimated emission of nucleons in jets, the available phase-space is limited. As a result, the production of nuclear states through coalescence in jets is expected to be enhanced compared to production in underlying events. In this contribution, the results for the coalescence parameter B2, which quantifies the formation probability of deuterons by coalescence, measured in and out of jets with the ALICE detector at the Large Hadron Collider, are presented and discussed in the context of the coalescence model.
