Abstract	Heavy-flavor measurements in ultrarelativistic hadronic collisions hold significance in validating perturbative QCD. The recent observation of an enhanced baryon-tomeson ratio at the low transverse momenta in hadronic collisions compared to e+e − and e −p collisions has disproven the universality of fragmentation fractions across colliding systems. Discrepancies between experimental measurements in hadronic collisions and models that rely on fragmentation functions constrained to e+e − and e−p data have also been obsereved. Charm-tagged jets measurements and azimuthal correlations between charmed hadrons and other charged particles offer supplementary insights into charm fragmentation mechanisms.
