"Color Outside the Lines: The search for multijet physics at the LHC"

The search for new colored particles at the LHC is a critical test for natural supersymmetric models.  I will review the status of these searches and explore scenarios that are not adequately covered by current analyses.  In particular, I will focus on a new proposal to search for high-multiplicity hadronic final states using large-radius jets.  Our recent work in this area has shown that jet mass and substructure are powerful discriminants between signal and QCD background.  This approach allows for the determination of QCD backgrounds using data-driven methods, which is crucial for the feasibility of any search that targets signatures with many jets and suppressed missing energy.
