Within the context of a hybrid strong/weak coupling model of jet quenching,we study the modification of the angular distribution of the energy within jetsin heavy ion collisions, as partons within jet showers lose energy and getkicked as they traverse the strongly coupled plasma produced in the collision.To describe the dynamics transverse to the jet axis, we add the effects oftransverse momentum broadening into our hybrid construction, introducing aparameter $K\equiv \hat q/T^3$ that governs its magnitude. We show that,because of the quenching of the energy of partons within a jet, even when$K\neq 0$ the jets that survive with some specified energy in the final stateare narrower than jets with that energy in proton-proton collisions. For thisreason, many standard observables are rather insensitive to $K$. We propose anew differential jet shape ratio observable in which the effects of transversemomentum broadening are apparent. We also analyze the response of the medium tothe passage of the jet through it, noting that the momentum lost by the jetappears as the momentum of a wake in the medium. After freezeout this wakebecomes soft particles with a broad angular distribution but with net momentumin the jet direction. We show that the particles coming from the response ofthe medium to the momentum and energy deposited in it leads to a correlationbetween the momentum of soft particles well separated from the jet in anglewith the direction of the jet momentum, and find qualitative but notquantitative agreement with experimental data on observables designed toextract such a correlation. By confronting the results that we obtain uponintroducing transverse momentum broadening and the response of the medium tothe jet with available jet data, we highlight the importance of these processesfor understanding the internal, soft, angular structure of high energy jets.
