BOOST COVARIANT GLUON DISTRIBUTIONS IN LARGE NUCLEI

It has been shown recently that there exist analytical solutions of th e Yang-Mills equations for non-Abelian Weizsacker-Williams fields whic h describe the distribution of gluons in large nuclei at small x. Thes e solutions however depend on the color charge distribution at large r apidities. We here construct a model of the color charge distribution of partons in the fragmentation region and use it to compute the boost covariant momentum distributions of wee gluons. The phenomenological applications of our results are discussed. (C) 1998 Elsevier Science B .V.
