Description
We address the problem of the resummation of Abelian clustering logarithms in QCD jet observables for jets defined using the kt, CA and SISCone algorithms. We specifically choose the jet mass distribution as an example and calculate up to O(alpha_s^4) clustering-logarithm coefficients to single log accuracy. We hence show that these logarithms exhibit a pattern of exponentiation and provide a resummed result for this distribition including non-global logarithms in the large-N_c limit. We show that the resummed result we provide here, although does not fully account for all single logs, is a very good analytic approximation for the fully resummed result obtained using a numerical Monte Carlo progam.
