We compute the leading clustering (abelian non-global) logarithms, which arise in the distribution of non-global QCD observables when final-state partons are clustered using the kt jet algorithm, up to six loops in perturbation theory. Our calculations are based on the recently introduced formula for the analytic structure of kt clustering [1]. These logarithms exhibit a pattern of exponentiation and are subsequently resummed into an exponential form. We compare this resummed result with all-orders numerical calculations.
