Description
Multi-charm baryons containing multiple charm quarks provide a unique window on uncovering the hadronisation mechanism in the quark-gluon plasma (QGP). The production yield of multi-charm baryons from single hard scattering is negligible compared to the one by coalescence of charm quarks from multiple hard scatterings. In Pb–Pb collisions, multi-charm baryon can be formed by a combination of charm quarks which are formed in independent hard scatterings, leading to an increase of the yield by up to 3 orders of magnitude compared with that in pp collisions.
ALICE 3, the next-generation heavy-ion programme for LHC Run 5, will offer an advanced opportunity to understand QGP, measuring the multi-charm baryon production from proton-proton to heavy-ion collisions. This contribution will present the performance study of $\rm \Xi^{++}_{\rm cc}$ via decays into the non-strangeness channel in pp collisions at $\sqrt{s}$ = 14 TeV with ALICE 3.
