Description
The energy-flow-operator (EFO) provides an idealised field-theoretic definition of a calorimenter. Recently, the angular correlations between EFOs on the celestial sphere have seen a great deal of interest as a tool for jet substructure. Due to the causal structure of EFO correlators, the angular size of the correlations can be viewed as a time parameter: early time perturbative correlations are imprinted at large angles, whilst later time correlations from hadronisation appear at small angles. In this work we demonstrate that the scales associated with the early time evolution (quenching) of a jet propagating through the QGP are imprinted in the large-angle perturbative structure of the 2-point correlator.
