We study the production of a heavy charged Higgs boson at the Large Hadron Collider (LHC) in gb→ H- t within a Two Higgs Doublet Model (2HDM). The chiral structure of the H- t 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 Electro-Weak Symmetry Breaking (EWSB). Taking two benchmark models (2HDM type-I and 2HDM type-Y) as an example, we show that inclusive rates, differential distributions as well as forward-backward asymmetries of the top quark's decay products can be used to search for heavy charged Higgs bosons as well as a model discriminators.
