Investigation of charm-quark hadronization into baryons in hadronic collisions with ALICE

초록

A comprehensive investigation into charm-baryon production provides insight into understanding charm-quark hadronization process. In this contribution, the charm-quark hadronization mechanism is discussed in terms of the production yield ratio between charm hadron species measured by ALICE Collaboration. Measurements of Lambda(+)(c), Sigma(0,++)(c) ,Xi(0,+)(c) and Omega(0)(c) in pp collisions, Lambda(+)(c) and Xi(0)(c) in p-Pb collisions are presented, together with the Lambda(+)(c) measurement in larger collision systems, Pb-Pb collisions. Furthermore, the charm-quark hadronization mechanism is discussed based on the fragmentation fractions computed for pp and p-Pb collisions. A preliminary result on Sigma(0,++)(c) measurement with Run 3 data is also presented.
