Dijet mass up to four loops with(out) $${{\varvec{k}}}_{\varvec{t}}$$ k t clustering by K. Khelifa-Kerfa

“…The calculations, performed within the eikonal approximation and employing strong-energy ordering, capture the full analytic structure of the leading Abelian and non-Abelian non-global logarithms, including full colour and jet-radius dependence. We evaluate the significance of these logarithms and the convergence of the four loop perturbative expansion by comparing with all-orders numerical results.…”

Leading-colour-based unweighted event generation for multi-parton tree-level processes by Rikkert Frederix, Timea Vitos

“…We introduce a two-step approach, in which initially unweighted events are generated at leading-colour (LC) accuracy, followed by a reweighting of these events to full-colour (FC) accuracy and applying an additional unweighting cycle. …”
