Jet suppression from a small to intermediate to large radius

Abstract

We present predictions for jet suppression from small to intermediate to very large radius, for high energy jets created in heavy ion collisions at the LHC. We find that jet suppression is surprisingly independent of the anti-kT radius R , first slightly increasing as one increases R , then at larger values of R very slowly decreasing. This behavior arises from two competing effects, namely the larger energy loss of the hard jet components, which tends to increase suppression, versus the partial recovery of the lost energy due to medium response, reducing suppression.
