Description

We present an interface between the multipurpose Monte Carlo tool MadGraph5aMC rate at NLO and the automated amplitude generatorGoSam.As a first application of this novel framework, we compute the NLO corrections to pp → t anti tH and pp → t anti tγγ matched to a parton shower. In the phenomenological analyses of these processes, we focus our attention on observables which are sensitive to the polarisation of the top quarks. (orig.)
