Jets are the collimated bunches of hadrons measured in our detectors, created at high energy particle collisions. As we go to higher energies at the Large Hadron Collider (LHC), Higgs bosons, or yet undiscovered heavy particles are produced with very high energy and the decay products from these "boosted" particles tend to be contained in jets that are spread over a larger area. The internal structure of these jets is exploited to identify the original particles that have decayed into the jets detected. In this seminar, I will motivate the use of substructure techniques for probing new physics at the LHC. I will then discuss the recent experimental results on substructure measurements, and conclude with introducing a relatively new and promising method called "shower deconstruction".
