Simplifying strangeness fluctuations through balance functions in proton–proton collisions
Recent measurements of event-by-event fluctuations of multistrange baryons and kaons in proton–proton collisions by ALICE have been proposed as sensitive probes to distinguish between thermal and string-based hadronization mechanisms. We demonstrate that two key observables – the normalized net-Ξ second-order cumulant and the net-K–net-Ξ Pearson correlation coefficient – can be re-expressed in ter
