The left–right twin Higgs (LRTH) model predicts the existence of the charged Higgs ϕ±. In this paper, we study the production of the charged Higgs boson ϕ- with single top quark via the process bg → tϕ- at the CERN Large Hadron Collider (LHC). The numerical results show that the production cross-section can reach the level of 10 pb in the reasonable parameter space of the LRTH model. We expect that, as long as it is not too heavy, the possible signatures of the heavy charged Higgs boson ϕ-> might be detected via the decay mode [Formula: see text] at the LHC experiments.

We study the production of a heavy charged Higgs boson at the Large Hadron Collider (LHC) in [Formula: see text] within a 2-Higgs Doublet Model (2HDM). The chiral structure of the [Formula: see text] 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 In this paper, we investigate sizeable interference effects between a heavy charged Higgs boson signal produced dominantly via $$ gg\to t\overline{b}{H}^{-} $$ gg → t b ¯ H − (+ c.c.) followed by the decay $$ {H}^{-}\to b\overline{t} $$ H − → b t ¯ (+ c.c.) and the irreducible background given by $$ pp\to t\overline{t}b\overline{b} $$ pp → t t ¯ b b ¯ topologies at the Large Hadron Collider (LHC). We show that it may be possible that such effects could spoil current H± searches where signal and background are normally treated separately. The reason for this is that a heavy charged Higgs boson can have a large total width, in turn enabling such interferences, altogether leading to potentially very significant alterations, both at the inclusive and exclusive level, of the yield induced by the signal alone. This therefore implies that currently established LHC searches for such wide charged Higgs bosons might require modifications. We show such effects quantitatively using two different benchmark configurations of the minimal realisation of Supersymmetry, wherein such H± states naturally exist. However, on the basis of the limited computing resources available, we are unable to always bring the statistical error down to a level where all such interference effects are unequivocal, so that we advocate dedicated experimental analyses to confirm this with higher statistics data samples.
