Power series distributions in clan structure analysis: new observables in strong interactions

Abstract

We present a new thermodynamical approach to multiparticle production in high energy hadronic interactions, making use of the formalism of infinitely divisible power series distributions. This approach allows us to define new observables, linked to the system fugacity, which characterise different classes of events.
