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

Abstract

Abstract We investigated the production of charmed baryons with different isospin and strangeness content, compared to both charmed D0 mesons and to the Λ c + 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.
