Abstract
Recent results from ALICE and CMS show a low-transverse-momentum enhancement
of charm baryon-to-meson production ratios over model predictions based on
e$^+$e$^-$ collisions. Several mechanisms are proposed to understand this
phenomenon. New measurements by the LHCb and ALICE experiments show a similar
enhancement in the beauty sector. We explore this enhancement in terms of event
activity using the color-reconnection beyond leading order approximation model.
We propose sensitive probes relying on the event shape that will allow for the
differentiation between the proposed beauty-production scenarios using freshly
collected LHC Run-3 data, and we also compare these to predictions for charm.
Our results will contribute to a deeper theoretical understanding of the
heavy-flavor baryon enhancement and its relation to baryon enhancement in
general.
