Higgs Discovery through Top-Partners using Jet Substructure

TL;DR

This paper demonstrates that jet substructure techniques enable the discovery of light Higgs bosons from top-partner decays at the LHC with relatively low integrated luminosity, especially for top-partner masses up to 1 TeV.

Contribution

It introduces a novel application of jet substructure methods to detect Higgs bosons from top-partner decays in new physics models at the LHC.

Findings

Light Higgs bosons can be discovered with less than 10 fb⁻¹ at 14 TeV LHC.

Jet substructure techniques effectively identify boosted Higgs decays to b b-bar.

Discovery potential extends to top-partner masses up to 1 TeV.

Abstract

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.
