b b W+ W- production at hadron colliders. Top signal and irreducible backgrounds
A. Ballestrero, E. Maina, M. Pizzio
Abstract
We compute complete tree level matrix elements for gg , q q → b 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.
