The ATLAS and CMS experiments are increasingly making use of jet substructure techniques in the search for new physics. By exploiting the energy and angular correlation structure within a jet, it is possible to differentiate between jets originating from light-quarks and gluons and jets from hadronically-decaying massive particles. Such techniques allow for the creation of new hadronic analyses, including di-tagged-jet resonances, single-jet mass scan searches, and searches for pair-produced vector-like quarks with complex hadronic final states. The sensitivities of these new searches are typically limited by the precision of the jet four-vector (especially the jet mass) and the ability to identify jets containing hadronically-decaying massive particles. Studies into new methods and tools to further extend the power of jet substructure techniques are very promising, and are set to further expand the relevance of jet substructure in the search for new physics.
