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

Abstract

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