Description
In this talk, we present a comprehensive summary of recent heavy-flavor results from the ALICE experiment, based on the high-statistics data collected during LHC Run 3. Heavy quarks (charm and beauty), produced in the early stages of high-energy collisions, serve as powerful probes of Quantum Chromodynamics (QCD) across different collision systems. In proton--proton (pp) collisions, they offer a means to validate perturbative QCD and investigate hadronization processes. In heavy-ion collisions, they probe the quark–gluon plasma (QGP) through their interactions with the medium.
With major detector upgrades the ALICE experiment achieved significantly improved precision, vertexing, and statistical reach in Run 3 enabling detailed exploration of heavy-flavor production across a broad kinematic range. We highlight key results from pp collisions at $\sqrt{s} = 13.6$ TeV, including baryon-to-meson production ratios, angular correlations, and the reconstruction of excited and rare charm and beauty hadrons.
In Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.36$ TeV, new measurements of charm-hadron elliptic flow ($v_2$), including the first $\Lambda_{c}^{+}$ $v_2$, provide valuable constraints on the degree of charm-quark thermalization and the interplay between partonic collectivity and hadronization.
Collectively, Run 3 has significantly advanced heavy-flavor studies in ALICE, delivering precise constraints on theoretical frameworks and enhancing our understanding of QCD in both small and large systems.
