Abstract

In this contribution we discuss recent progress in associated top-quark pair production with one or two isolated photons, $pp\to t\bar{t}\gamma(\gamma)$. 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.

Report

The manuscript provides a detailed discussion of the associated top-quark pair production with one or two isolated photons. It addresses the inclusion of higher order effects and photon radiation in both production and decay processes. Their results show that these contributions are very relevant for robust theoretical predictions.

The manuscript is well-motivated, clearly written, and the results are highly relevant for the LHC community. Therefore, I recommend this manuscript for publication.
