Heavy-ion collisions at high energy

Journal Article · · Phys. Rev. C; (United States)
;
Relativistic heavy ion collisions are studied here taking into account the hard scattering model of Schmidt and Blankenbecler along with a dynamical derivation of the inclusive distribution for pp..--> pi..x, pp..-->..Kx, and pp..-->..p-barx and pp..-->..px proposed in an earlier paper. This scheme takes into account scale breaking and it is found that both A and B dependence occur in such processes as AB..--> pi../sup -/x, AB..-->..K-barx, AB..-->..p-barx, and AB..-->..px in the forward region. In the backward region the independent N-N collision model is also found satisfactory when the structural rearrangement factor is incorporated in the vertex function. It is found that although in the forward region scale breaking is not appreciable, it becomes quite significant in the backward region. The x distributions in the forward region as well as in the backward region have been computed on the basis of this independent N-N collision model. The results are found to be in very good agreement for inclusive pion production.
