Event-activity-dependent production of strange and non-strange charmed baryons in the enhanced color-reconnection scheme

Abstract

We investigated the production of charmed baryons with different isospin and strangeness content, compared to both charmed D0 mesons and to the baryon in proton–proton collisions at LHC energies. We used the PYTHIA 8 Monte Carlo event generator with color reconnection beyond leading-color approximation and proposed methods based on event-activity classifiers to probe the source of the charmed-baryon enhancement. We conclude that in the considered model class, the isospin of the charmed-baryon state has a strong impact on the enhancement pattern. Using the observables we propose, upcoming high-precision experimental data will be able to differentiate between mechanisms of strangeness and charm enhancement.
