- W4320085990 abstract "Studies of open-charm hadron production in pp and pPb collisions are performed by the ALICE Collaboration at the LHC to investigate charm-quark hadronization mechanisms. Recent measurements of charm meson (${rm D^0}$, ${rm D^+}$, ${rm D^+_{rm s}}$, and ${rm D^{*+}}$) and baryon ($Lambda^+_{rm c}$, $Xi^{0,+}_{rm c}$, $Sigma^{0,++}_{rm c}$, and $Omega^0_{rm c}$) production in pp collisions at $sqrt{s}$ = 5.02 TeV and $sqrt{s}$ = 13 TeV allow the determination of the charm cross section and the fragmentation fractions at $sqrt{s}$ = 5.02 TeV with unprecedented precision. The measurements show that the fragmentation fractions significantly differ from the ones measured in ${rm e^+e^-}$ and ep collisions. This highlights possible differences in the hadronization process between electron induced collisions and pp collisions at the LHC. Furthermore, the first measurement of the baryon-to-meson yield ratio $Lambda^+_{rm c}/{rm D^0}$, down to $p_{rm T}=0$ in pp and pPb collisions will be discussed. In p--Pb collisions a modification of the hadronization mechanisms could be present due to cold nuclear matter effects and collective phenomena. A systematic comparison between data and model calculations will help to understand charm quark hadronization in pp and p--Pb collisions." @default.
