Abstract
We report on an NLO simulation of W+W−b ̄b production with massive b-quarks at the LHC.Thanks to the finite b-quark mass, W+W−b ̄b predictions can be extended to the whole b-quarkphase space, thereby including Wt-channel single-top contributions that originate from collinearg→b ̄b splittings, and quantum interference effects. The simulation is also applicable to exclusive0- and 1-jet bins, which is of great importance for Higgs-boson studies in the H→W+W−channeland for any other analysis with large top backgrounds and jetvetoes or jet bins
