Rapidity distribution of gluons in the classical field model for heavy ion collisions
چکیده
The rapidity distribution of gluons produced in heavy ion collisions is studied by a numerical computation in 2+1-dimensional classical Yang-Mills theory. By assuming that the classical source strength gμ depends on rapidity as gμ ∼ e and studying collisions of two nuclei with different gμ we find that the rapidity distribution of produced gluons at central rapidities is very broad. The transverse energy is seen to decrease even more slowly as a function of y than the multiplicity. We discuss these results and the range in y and √ s where they are applicable in the light of experimental results and other theoretical calculations.
