Hydrodynamical Treatment of Multiple Meson Production in High Energy Nucleon-Nucleus Collisions

Abstract

The multiple meson production in high energy nucleon-nucleus collisions is treated by extending Landau's hydrodynamical model which is supported not only from experimental data on cosmic ray, but also from some theoretical point of view. As we have much data on the nucleon-nucleus collisions rather than on elementary collisions, we may get some clue to the future theory by comparing our results with the data on cosmic ray, though the latter are very complicated and our theory is somewhat phenomenological. Theoretical results are derived focusing on the dynamical properties of secondary particles, such as the effective inelasticity, energy and angular distributions and transverse momenta; and their dependence on the size of nucleus is considered.
