Description

Jets — collimated sprays of particles from high-energy quarks and gluons— lose energy when traversing the quark--gluon plasma, a phenomenon known as \emph{jet quenching}. We develop an analytic framework that captures this process through a turbulent gluon cascade, driven by medium-induced splittings at all angles. A non-linear rate equation, amplified by the medium length $L$, connects to a DGLAP-like evolution for the early collinear cascade above the medium resolution scale $\theta_c$. At high energies, the cascade exhibits an exponential energy-loss pattern, generalizing the classic Poisson model, and enabling resummation of leading $\alpha_s$ logarithms and $\alpha_s L$ effects. This approach also yields analytic insight into the strong-quenching regime, guiding future simulations.
