Using the coalescence model with nucleon and Lambda phase-space distributions generated by the hybrid MUSIC framework, we study the elliptic flow (v 2) and triangular flow (v 3) of (anti-)protons, (anti-)deuterons, (anti-)3He, and Λ 3 H in Pb+Pb collisions at s N N = 5.36 TeV. We find that the simple v 2 scaling with the number of constituent nucleons A breaks down at high transverse momentum pT /A > 1.5 GeV/c, while an improved scaling relation holds well up to pT /A ≈ 3 GeV/c. In contrast, v 3 exhibits similar behavior under both scaling prescriptions, with no significant difference. We also make predictions for v 2 and v 3 of the hypertriton and find these flows are insensitive to the Lambda-deuteron ( Λ − d ) distance inside the hypertriton. Our results are compared with preliminary experimental measurements by the ALICE Collaboration and offer insight into the production mechanisms of light (anti-)(hyper-)nuclei in high-energy heavy-ion collisions.
