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 g2\ensuremathμ depends on rapidity as g4\ensuremathμ2\ensuremath∼e^\ifmmode±\else\textpm\fi\ensuremathλy and studying collisions of two nuclei with different g2\ensuremathμ, 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.
