The two-jet rate in e^+e^- at next-to-next-to-leading-logarithmic order
arXiv:1607.03111 · doi:10.1103/PhysRevLett.117.172001
Abstract
We present the first next-to-next-to-leading logarithmic resummation for the two-jet rate in 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.
