Title: Energy dependence of KNO moments using the Novero–Predazzi method with a new ansatz
Abstract: The method of Novero–Predazzi is applied to a new ansatz with three constraints. Hadronic production cross sections σ n (s) satisfying Koba–Nielsen–Olesen (KNO)-like constraints are determined; σ n (s) and [Formula: see text] automatically have the KNO scaling property. The multiplicity distribution P n obtained is identical with the empirical formula used by Bozóki et al. The generalization of the method is investigated for more than three constraints. Assuming a given energy dependence of the parameter in the KNO function, we find that all calculated higher moments c k of the KNO function are in excellent agreement with the observed values of c k – s for proton–proton (pp) interactions at Serpukhov, the Fermi National Accelerator Laboratory (FNAL), and intersecting storage rings' (ISR) energies.A zero parameter empirical formula is presented, which gives good results at a 95% confidence level for pp interactions. This KNO function describes the multiplicity distributions e + e − at positron–electron tandem ring accelerator (PETRA) energies. We give a dynamical ansatz leading to this KNO function within the framework of a parton model.
