Searching for heavy charged Higgs bosons through top quark polarization

Searching for heavy charged Higgs bosons through top quark polarization
We study the production of a heavy charged Higgs boson at the Large Hadron Collider (LHC) in gb→H−t within a 2-Higgs Doublet Model (2HDM). The chiral structure of the H+t̄ b coupling can trigger a particular spin state of the top quark produced in the decay of a charged Higgs boson and, therefore, is sensitive to the underlying mechanism of the Electroweak Symmetry Breaking (EWSB). Taking two benchmark models (2HDM type-I and 2HDM type-Y) as an example, we show that inclusive rates, differential distributions and forward–backward asymmetries of the top quark’s decay products can be used to search for heavy charged Higgs bosons and also as model discriminators.

Abstract

We study the production of a heavy charged Higgs boson at the Large Hadron Collider (LHC) in gb→H−t within a 2-Higgs Doublet Model (2HDM). The chiral structure of the H+t̄ b coupling can trigger a particular spin state of the top quark produced in the decay of a charged Higgs boson and, therefore, is sensitive to the underlying mechanism of the Electroweak Symmetry Breaking (EWSB). Taking two benchmark models (2HDM type-I and 2HDM type-Y) as an example, we show that inclusive rates, differential distributions and forward–backward asymmetries of the top quark’s decay products can be used to search for heavy charged Higgs bosons and also as model discriminators.
