Complete NLO corrections to $t\bar{t}\gamma$ and $t\bar{t}\gamma\gamma$
Abstract
In this contribution we discuss recent progress in associated top-quark pair production with one or two isolated photons, pp\to t\bar{t}\gamma(\gamma) p p → t t ‾ γ ( γ ) . The focus is the simultaneous inclusion of higher-order effects and photon radiation in the production of the top-quark pair and in the decay processes. This allows us to quantify the importance of photon radiation in decay processes and the size of the so-called complete NLO corrections in realistic final states.
