Description
One of the intrinsic features of parton's energy loss is the evident flavor dependence. Inspired by the dead-cone effect in radiative energy loss and experimentally detected suppression mass hierarchy, we address the mass ordering in heavy flavor suppression.
While mass hierarchy is analyzed within radiative models, collisional interpretation is still lacking. To this end, we apply recently developed DREENA framework, which is based on our dynamical energy loss formalism. Within this [1] we provide 1) A novel observable, which can disentangle collisional from radiative energy loss, to be rigorously tested by the upcoming high-precision measurements at RHIC and LHC; 2) Analytical derivation of a direct relation between collisional suppression/energy loss and heavy quark mass; 3) Analytical and numerical extraction of the mass ordering in collisional energy loss through this observable.
