Power counting energy flow polynomials

Power counting is a systematic strategy for organizing collider observables and their associated theoretical calculations. In this paper, we use power to characterize class of jet substructure called energy flow polynomials (EFPs). EFPs provide an overcomplete linear basis infrared-and-collinear safe observables, but it known that in practice, small subset often sufficient specific analysis tasks. By applying arguments, obtain relationships between hold quark gluon jets order the counting. We test these relations parton shower generator Pythia, finding excellent agreement. allows us truncate without affecting performance, which corroborate through study quark-gluon tagging regression.
