Description
I present theoretical predictions for the production of a W-boson in association with a bottomquark pair at hadron colliders at next-to-next-to-leading order (NNLO) in QCD, including the leptonic decay of the W-boson, while treating the bottom quark as massless. This calculation constitutes the very first $2 \to 3$ process with a massive external particle to be studied at such a perturbative order. Numerical results for the cross section and differential distributions are presented for the Large Hadron Collider. The definition of IRC-safe flavoured jets becomes subtle beyond NLO QCD. I discuss the application of a proposed flavour safe anti-kT algorithm to this process and discuss the phenomenology.
