The Standard Model (SM) is a low-energy effective theory with no explanation of dark matter (DM), gravity, or the matter-antimatter asymmetry in the universe. Even the recently discovered Higgs boson requires some new physics (NP) to avoid unnatural fine-tuning of its mass. The Large Hadron Collider (LHC) was built to test various answers to these and other open questions. New models often include heavy resonances and with enhanced parton luminosities due to the increased center of mass energy for Run 2, the discovery potential is considerable. With no preferred candidate theory, we must push our understanding of the SM to new extremes and test all viable extensions. To highlight this exciting time, some of the first searches hunting for new heavy particles using high pT jets in Run 2 data collected by the ATLAS collaboration will be discussed.
