In order to investigate soft gluon evolution at NLO (next‐to‐leading order) the oneloop/-one‐emission and two‐loop Feynman‐diagrams have to be analysed.
I will give an introduction to the colour‐space formalism, and discuss the evolution equations in colour space to resum non‐global observables.
I will highlight the colour‐flow basis as it not only provides immediate physical interpretation but it is also efficient in numerical approaches for soft gluon evolution.
