Title: Probing jet decoherence in heavy ion collisions

Abstract

We suggest to use the SofDrop jet grooming technique to investigate the sensitivity of jet substructure to color decoherence in heavy ion collisions. We propose in particular to analyze the two-prong probability angular distribution as a probe of the transition between the coherent and incoherent energy loss regimes. Also, we predict an increasing suppression of two-prong substructures with angle as the medium resolves more jet substructure.
