Abstract

Recent measurements of charm-baryon production in proton--proton (pp) collisions at midrapidity by the ALICE collaboration showed that baryon-to-meson yield ratios are significantly higher than those measured in \rm e⁺e^- collisions. The charm baryon-to-meson and charm baryon-to-baryon yield ratios provide unique information on hadronization mechanisms since the contributions from parton distribution function and parton--parton scattering terms cancel in the ratios. In this contribution, the first measurement of \rm Ω_c⁰ production via the hadronic decay channel \rm Ω_c⁰ → Ω^-π⁺ (and its charge conjugate) in 2
