Studying charm-quark hadronization via charm-baryon production measurements in pp collisions at the LHC with ALICE

Key Points

This research aims to investigate charm-quark hadronization through the production of charm baryons in proton-proton collisions.
Measured various charm-baryons including Ξc0,+ and Λc+, ∑c0,++ in pp collisions at 13.6 TeV.
Analyzed the cross-section ratio of different charm-baryon states and their angular correlations.
First measurements of ∑c0,++(2520)/∑c0,++(2455) cross-section ratio reported.
Λc+ −p angular correlation data provided new insights into baryon production.

Abstract

In these proceedings, the measurements of strange (Ξc0,+) and non-strange (Λc+, ∑c0,++) charm-baryon production are reported. Moreover, the first measurements of the ∑c0,++(2520)/∑c0,++(2455) cross-section ratio and Λc+ −p angular correlation are discussed utilizing the large data sample of pp collisions at √s = 13.6 TeV collected during LHC Run 3. These results are compared with various theoretical model predictions.
