Abstract

We compute the invariant mass of dijets produced in e⁺ e^- annihilation processes up to four loops in perturbation theory for both anti-k_t and k_t jet algorithms. 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.
