Charged Higgs bosons in single top production at the LHC

Understand

We show that a light charged Higgs boson signal via $\tau^\pm\nu$ decay can be established at the Large Hadron Collider (LHC) also in the case of single top production.

• This process complements searches for the same signal in the case of charged Higgs bosons emerging from $t \bar t$ production.
• The models accessible include the Minimal Supersymmetric Standard Model (MSSM) as well a variety of 2-Higgs Doublet Models (2HDMs).
• High energies and luminosities are however required, thereby restricting interest on this mode to the case of the LHC running at 14 TeV with design configuration.
