Description
Jet angularity is a classic substructure observable which probes the angular distribution of jet constituents. While soft-drop grooming may suppress complicated contributions from wide-angle, soft radiation, the dependence on jet algorithm also limits the theoretical precision to higher accuracy. In this work we provide resummed calculations of flattened jet angularity which generalizes the power-law angular weight to generic functions using soft-collinear effective theory. This observable provides a new and flexible way of probing jet substructure phase space with applications in boosted particle tagging and hard probes of nuclear matter.
