Pressing particle physics questions are left unanswered by the Standard Model theory, even after the discovery of the Higgs Boson. These questions include the hierarchy problem, the nature of gravity and dark matter. New models often predict massive new resonances that have substantial decay rates to bosons. The discovery potential at the LHC is considerable given the enhanced parton luminosities due to the increased center-of-mass energy in the LHC Run II. Novel techniques have been developed for searches in the hadronic decay channels that increase the sensitivity to heavy masses. I will describe the developments in jet substructure methods and boson tagging and their recent applications in ATLAS searches.
