  In heavy-ion and hadronic collisions, indications of thermalization are
detected in the yields of produced hadrons: these observations call for a
detailed study of the hadronization processes. Novel observables are required
to discriminate between the different hadronization models that successfully
describe the average yields of hadrons. The ALICE Collaboration reports on the
studies of event-by-event fluctuations of the net-$\Xi^\pm$ number, and Pearson
correlations of both the net-$\Xi^\pm$-net-kaon numbers and the
antideuteron-antiproton numbers, in pp, p-Pb, and Pb-Pb collisions. The
measured fluctuations are compared with different hadronization models to
explore the compatibility with a charge-equilibration scenario. In all cases,
the experimental data agree with Thermal-FIST canonical-statistical
calculations, allowing for the extraction of the correlation length for strange
and baryon quantum number conservation.
