Description
Jets are excellent probes for the study of the deconfined matter formed in heavy ion collisions. In particular, jet substructure measurements can help us understand the interaction dynamics of high-energy partons with the quark-gluon plasma. We introduce a new infrared and collinear safe observable: jet energy flow measurements using jets reconstructed with different resolution parameters $R$. These measurements can help us gauge the competition between the dependence of energy loss on the opening angle of the shower on the one hand and the generation of large-angle fragments by radiative energy loss which give opposite trends for the R-dependence of the nuclear modification factor. In this poster we present a first measurement of jet energy flow in JEWEL simulations, and highlight its sensitivity to jet energy loss and medium recoil effects.
