Modification of heavy quark hadronization in high-multiplicity collisions at LHCb

The ratio of heavy flavor hadrons is very sensitive to the hadronization mechanism. This proceeding will present recent LHCb results on the cross-section ratios of $D_s^{+}\mathrm{/}{D}^{+}$, ${\mathrm{\Xi }}_c^{+}\mathrm{/}{\mathrm{\Lambda }}_c^{+}$ and ${\mathrm{\Lambda }}_b^0\mathrm{/}{B}^0$ in different collision systems. The significantly enhanced production ratios $D_s^{+}\mathrm{/}{D}^{+}$ and ${\mathrm{\Lambda }}_b^0\mathrm{/}{B}^0$ with the increase of multiplicity may imply that hadronization mechanisms are modified in high-multiplicity events.
