$b b ˉ W^{+} W^{-}$ production at hadron colliders. Top signal and irreducible backgrounds

Abstract

We compute complete tree level matrix elements for $g g, q q ˉ \to b b ˉ W^{+} W^{-}$ . 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.
