Finite angle effects in jet quenching

The medium that forms in a heavy-ion collision modifies the properties of jets traversing it. These modifications give substantial information about nature and, therefore, they are one main focuses program at LHC. influence into highly energetic partons depends on correlators Wilson lines, which have been studied perturbation theory and several phenomenological models. Here, we focus antenna configuration, study evolution large energy resulting from collinear splitting inside medium. In eikonal limit, interaction each daughter parton with can be parametrized by light-like line given direction. We consider case angle between these two directions θ is small but such Lθ order resolution scale, where L size find finite effects sub-leading corrections to jet broadening. physical effect configuration make decoherence larger when taken account.
