Abstract
In this talk an interface is presented between the multi-purpose next-to-leading-order Monte Carlo tool MadGraph5_aMC@NLO and the automated one-loop amplitude generator GoSam. As a phenomenological application of this work, the interface is used to make predictions for the t-tbar-Higgs and t-tbar-gamma-gamma processes at the 13 TeV LHC. The differences between these two processes is studied, focussing in particular on observables that are sensitive to the polarisation of the top quarks.
