Description
Recent measurements of hadron production have revealed a non-universal behaviour in the fragmentation of partons into baryons in hadronic collisions compared to baselines in $e^+e^-$ and ep collisions. Exploration of this phenomenon is most controlled in the heavy-flavor sector, where the large mass of charm or beauty quarks allows us to experimentally relate a heavy-flavor parton to the resulting hadron. This allows for well-defined measurements of heavy-flavour jet fragmentation, enabling us to take steps beyond the traditional hadronic measurements to unveil the microscopic details of this non-universality.
In this talk, we present measurements of charm jets using jets tagged with reconstructed $\mathrm{D}^{0}$ mesons and $\Lambda_{c}^{+}$ baryons. Using the large data samples collected during Run3 at the LHC, the radial profiles of $\mathrm{D}^{0}$ and $\Lambda_{c}^{+}$-tagged jets are compared to directly probe charm hadronization mechanisms. Comparisons of these results to various event generators employing different hadronization tunes will also be discussed.
