Description
One of the primary goals of the Large Hadron Collider (LHC) is to search for new particles at the TeV scale. New TeV scale particles are needed to develop a physics understanding of the electroweak (EW) symmetry breaking and the structure of the Higgs field and are also fundamentally connected to the mystery of dark matter and other fundamental questions such as the unification of forces. Among the primary tools to explore the TeV scale at the LHC are the top quark, the vector bosons, and the Higgs boson. At the LHC, the efficienct identification of jets from the decay of heavy EW particles is particularly difficult due to two main reasons: the high center of mass energy relative to the EW scale, which leads to signatures of highly boosted EW heavy particles where classical reconstruction algorithms are inadequate, and the high pileup, multiple proton-proton interactions within a same bunch crossing, that contaminates the events. These challenges led to the development of a new suite of jet substructure and pileup mitigation techniques to fully exploit the discovery potential of the LHC experiments to new physics. In this talk I will describe the state-of-the-art and new developments in jet substructure, with a particular emphasis on methods to mitigate pileup, and the application of these methods to the search for new physics with very large number of jets for the first time at the LHC.
