Charm Quark Hadronisation Studies In pp Collisions With ALICE

In this contribution, the latest results for measurements of charm baryons in proton--proton collisions at $\sqrt{s}=5.02$ and $13\,\mathrm{TeV}$ are presented. The production yields of $\Lambda_\mathrm{c}^{+}$, $\Xi_\mathrm{c}^{0,+}$, $\Omega_\mathrm{c}^{0}$, and $\Sigma_\mathrm{c}^{0,++}$ are show...

description In this contribution, the latest results for measurements of charm baryons in proton--proton collisions at $\sqrt{s}=5.02$ and $13\,\mathrm{TeV}$ are presented. The production yields of $\Lambda_\mathrm{c}^{+}$, $\Xi_\mathrm{c}^{0,+}$, $\Omega_\mathrm{c}^{0}$, and $\Sigma_\mathrm{c}^{0,++}$ are shown along with their yield ratios to $\mathrm{D}^{0}$ mesons, and observations about charm hadronisation with respect to previous results from lepton colliders are discussed. Further differential measurements are shown of the $\Lambda_\mathrm{c}^{+}/\mathrm{D}^{0}$ yield ratio as a function of charged-particle multiplicity. For the first time, the production of $\Lambda_\mathrm{c}^{+}$ is presented in pp collisions down to $p_\mathrm{T} = 0$, and the total charm production cross section and relative charm hadronisation fractions in p--Pb collisions are computed.
