Multi-particle correlations and KNO scaling in the medium-induced jet evolution

Understand

We study the gluon distribution produced via successive medium-induced branchings by an energetic jet propagating through a weakly-coupled quark-gluon plasma.

• We show that under suitable approximations the evolution of the jet can be described as a classical stochastic process, which is exactly solvable.
• For this process, we construct exact analytic solutions for all the n-point correlation functions (the n-body densities in the space of energy).
• The corresponding results for the one-point and the two-point functions were already known, but those for the higher-point functions are new.
