Multiplicity structure of inclusive diffraction in À+ p andK + p interactions at 250 GeV/c

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

Results on the multiplicity structure of diffractively excited meson and proton systems in À+/K+ p interactions at 250 GeV/c are presented for diffractive masses up to about 9 GeV. The energy dependence of the average charge multiplicity and the shape of the multiplicity distribution in terms of KNO-scaling and negative binomial distribution are investigated. The diffractive systems are compared toe + e −,lh and non-diffractivehh final states as suggested by modern approaches of the Pomeron-hadron collision. Systematic differences are found between diffractive meson and proton systems but also between diffraction and the reactions compared to.
