ALFRED MUELLER Columbia University Jet dacays in a conformal theory do not terminate but go on forever producing ever softer quanta. Nonrenormalization theorems would seem to suggest that the spectrum is the same as in a free theory in which there is no jet branching. Resolving this "apparent" conflict in perturbation theory and in strong coupling, via AdS/CFT, is the topic of the seminar.
