Since the neutrinos are not detected, we average over them, indicated by the brackets. Hence, we have to be fully inclusive w.r.t. the neutrinos. Still, the code allows to make any cut on the other final-state particles. As we will see, the \ac{BR} for this process, as measured by {\sc BaBar}~\cite{Lees:2015gea, Oberhof:2015snl} has a discrepancy of more than $3\,\sigma$ from the \ac{SM} value. This will illustrate the importance of fully differential \ac{NLO} corrections in \ac{QED}. \input{run/setup} \input{run/walkthrough} \input{run/nlo} \input{run/exec} \input{run/analysis}
