Searching for a charged Higgs boson with both $H^{\pm}W^{\mp}Z$ and $H^{\pm}tb$ couplings at the LHC

Understand

In certain new physics scenarios, a singly charged Higgs boson can couple to both fermions and $W^\pm Z$ at tree level.

• We develop new strategies beyond current experimental searches using $pp\to jjH^\pm$, $H^\pm \to tb $ at the Large Hadron Collider (LHC).
• With the effective $H^\pm W^\mp Z$ and $H^\pm tb$ couplings we perform a model-independent analysis at the collision energy $\sqrt{s}=13$~TeV with the integrated luminosity of $3~\text{ab}^{-1}$.
• We derive the discovery prospects and exclusion limits for the charged Higgs boson in the mass range from 200~GeV to 1~TeV.
