Higgs Discovery through Top-Partners using Jet Substructure

Understand

Top-partners -- vector-like quarks which mix predominantly with the top quark -- are simple extensions of the standard model present in many theories of new physics such as little Higgs models, topcolor models, and extra dimensions.

• Through renormalizable mixing with the top quark, these top-partners inherit couplings to the Higgs boson.
• Higgs bosons produced from the decay of top-partners are often highly boosted and ideal candidates for analyses based on jet substructure.
• Using substructure methods, we show that light Higgs bosons decaying to b b-bar can be discovered at the 14 TeV LHC with less than 10 inverse fb for top-partner masses up to 1 TeV.
