Abstract

We present a quantitative study of energy flow away from jets by numerically solving the evolution equation derived by Banfi, Marchesini, and Smye, and apply the result to two processes at the LHC: discriminating high-p_t jets originating from decays of heavy electroweak bosons from the QCD background, and the survival probability of the BFKL-initiated dijet rapidity gaps. As a by-product, we find a hidden symmetry of the Banfi, Marchesini, and Smye equation which is a remnant of conformal symmetry.
