W and Z/γ∗ boson production in association with a bottom-antibottom pair


Frederix, R; Frixione, S; Hirschi, V; Maltoni, F; Pittau, R; Torrielli, P (2011). W and Z/γ∗ boson production in association with a bottom-antibottom pair. Journal of High Energy Physics, (9):61.

Abstract

We present a study of ell ν bbar{b} and {ell+ }{ell- }bbar{b} production at hadron colliders. Our results, accurate to the next-to-leading order in QCD, are based on automatic matrix-element calculations performed by M adLoop and M adFKS, and are given at both the parton level, and after the matching with the H erwig event generator, achieved with aMC@NLO. We retain the complete dependence on the bottom-quark mass, and include exactly all spin correlations of final-state leptons. We discuss the cases of several observables at the LHC which highlight the importance of accurate simulations.
