The increased pile-up expected in the LHC Run 2 and High Luminosity LHC creates a challenging environment for utilizing the jet-substructure techniques which were successfully demonstrated in the LHC Run 1. The ATLAS and CMS experiments are studying a range of methods to improve jet reconstruction to increase the resilience against high pile-up. Promising results are obtained in simulation but await validation on the first Run 2 data.
