On the Nature of the Average Transverse Momenta of the Low-pT Secondaries in Some High Energy Nuclear Collisions
ABSTRACT
That the values of average transverse momenta ( ) of the secondaries produced in high energy collisions rise very slowly with energy is modestly well-known and accepted. We would like to probe into this aspect of the problem for production of the main variety of the 'soft' secondaries in two high energy symmetric nuclear collisions with the help of two non-QCD models. Our model-based results are found to be quite consistent with the anticipated behaviours and also with the observations.
