A new measurement of jet splitting functions was recently presented for the first time at the Boost Workshop, and was then also highlighted at ICHEP. This study, in pp and PbPb collisions, which is sensitive to the impact of quenching on jet substructure, triggered interest both from the side of experimentalists and in the theory community. This Crosstalk will discuss the reconstruction techniques, the results, and the interpretation.
