On the properties of hadronic matter

Striking features peculiar to hadronic interactions, that is, the spectrum of resonances, duality and the quark-line rule (OZI rule) observed in accelerator experiments and the spectrum (M sub(n) asymptotically equalds (2 - 3) GeV x 10sup(n), n = 0, 1, 2) and new varieties (Centauro, Mini-Centauro, Geminion) of fireballs found in cosmic ray experiments are interpreted qualitatively in terms of a model of hadronic matter of which hadrons are made. And, the properties and the production and annihilation mechanism of the hadronic matter are inferred from the experimental facts. A characteristic of the model is a cutoff of the momentum degree of freedom of basic particles referring to a universal timelike vector. If this is really the case, fireballs with very large Lorents-factors should reveal peculiar properties in cosmic ray experiments. Those peculiar properties of fireballs cannot be observed in colliding-beam experiments where the Lorentz-factors of the fireballs are not sufficiently large. (author)
