摘要：
We improve previously derived analytical estimates of hadronisation corrections to QCD jets at hadron colliders, firmly establishing at the two-loop level the link to the well-known power corrections to LEP event-shape variables. The results of this paper apply to jets defined in the k(t) and anti-k(t) algorithms but the general framework presented here holds also for other algorithms for which calculations are in progress.
