摘要：
We compute complete tree level matrix elements for gg, <q(q)over bar> --> <b(b)over bar W+W->. We analyze the irreducible backgrounds to top signal at the Tevatron and at the LHC. Their contribution to the total cross section is about 5% at the LHC, due to single resonant channels. Several distributions with contributions from signal and backgrounds are presented.
