Two-jet rate in e+e- at next-to-next-to-leading logarithmic order

We present the first next-to-next-to-leading logarithmic resummation for the two-jet rate in e+e− annihilation in the Durham and Cambridge algorithms. The results are obtained by extending the ARES method to observables involving any global, recursively infrared and collinear safe jet algorithm in e+e− collisions. As opposed to other methods, this approach does not require a factorization theorem for the observables. We present predictions matched to next-to-next-to-leading order, and a comparison to LEP data
