Study of the Violation of KNO Scaling and the Validity of Modified KNO Scaling Based on the Cluster Model

Kiyoshi KUDO 0 0 Department of Applied Physics, Fukui University , Fukui 910 The violation of Koba-Nielsen-Olesen (KNO) scaling observed in the recent ffP collider experiments is explained by means

Analysis of Momentum and Multiplicity Distributions for High Energy Multiparticle Production Processes Based on the Thermal Three-Cluster Model-Simulation

Recent experimental data of the momentum and the multiplicity distributions in high energy hadronic reactions are reproduced well by a Monte Carlo simulation using thermal three-cluster model. Through the analyses it is pointed out that the rapidity distribution has a slight central dip in the present collider energy regions. We predict that this central dip should appear clearly...

Analysis of Intermittent Phenomena for High Energy Multiparticle Production Processes

Intermittent phenomena in η space are reproduced by a cluster model-simulation. It is pointed out that experimental data of the η distribution show the characteristic feature to be named intermittent phenomena which come from correlation effects of produced clusters. These phenomena should be distinguished from the so-called intermittency which is given by self-similar particle...

A Vacuum with Double Structure

For the purpose of proving the conservation of norm in the field theory of complex mass proposed by one of the present authors, a new space is introduced where the state vectors have a double structure and the norms are complex numbers in general. The new space contains the Hilbert space as a subspace where the norms are real and positive. It is shown that the S-matrix transforms...

Quantum Field Theory of Complex Mass. II

The main purpose of this paper is to further clarify some unsatisfactory points in our previous paper. First a new conjugation is introduced. The conjugation exists in the case of complex mass and is similar to the hermitian conjugation. Connections between these two conjugations are clarified. The transformation properties of some operators under these conjugations are studied...

Violation of the |ΔI|=1/2 Rule in K→3π Decays

The violation of the |ΔI|=1/2 rule in K →3 π decays is discussed on the assumption that the weak-interaction Hamiltonian has the pure |ΔI|=1/2 property and that the violation of the |ΔI|=1/2 rule is caused by the electromagnetic interaction. The assumptions of chiral SU3 ×SU3 algebra, P. C. A. C. and soft pion approximation are also used. The results are in good agreement with...

Meson Decays in the Dynamical Composite Model

The various three-meson-vertices M →M′+M′′ are examined on the basis of the dynamical composite model in which it is assumed that the mesons M and M′ are dynamical composite systems of urbaryon and anti-urbaryon and one of the final meson, M′′, is structureless. It should be noted that the transition matrix elements of the M →M′+M′′ decay processes contain only one parameter in...
