associated production at the LHC.

We study Higgs boson production in association with a top quark and a boson at the LHC. At NLO in QCD, interferes with [Formula: see text] and a procedure to meaningfully separate the two processes needs to be employed. In order to define production for both total rates and differential distributions, we consider the diagram removal and diagram subtraction techniques that have been previously proposed for treating intermediate resonances at NLO, in particular in the context of production.
