Description
Jets have proven to be a powerful experimental tool to ascertain the properties of the QGP. In this work, we propose a new class of jet substructure observables which, unlike fragmentation functions, are largely insensitive to the poorly known physics of hadronization. We show that intra jet sub-jet structures provide us with a large discriminating power between different jet quenching Monte Carlo implementations. Further, this new class of observables proves instrumental to isolate with high purity samples of strongly modified jets where the competing mechanisms of energy loss can be more easily disentangled.
