A model for multiple meson production in nucleon-nucleon collisions

Abstract

The double lump structure of the produced mesons and the persistency of the original nucleons in high energy nuclear interaction are found. An empirical model of multiple meson production in a nucleonnucleon collision is constructed on these experimental bases. Assuming the symmetry about the two colliding nucleons in C.M.S. the collision is divided into two parts belonging to each nucleon. And, a physical quantity named «momentum of interaction» is introduced, which is the momentum difference between the initial and final state in each part. This quantity is considered to be a parameter representing the magnitude of the effect of the interaction in the collision. The average value of this quantity in high energy jets are found to be of the order of unity in nucleon mass units independently from the incident energy. Taking as a working hypothesis an empirical relation between the «momentum of interaction» and the recoil momentum of the target nucleon in L.S. which is suggested in the analysis of one high energy jet, the details of the collision are determined in our model by the magnitude of the incident energy and that of the «momentum of interaction». This model can explain the variety of the experimental data of high energy jets which have been accumulated up to now. The physical significance of the basic assumptions of this model should be searched for in future.
