Optimising Charged Higgs Boson Searches at the Large Hadron Collider Across $b\bar{b}{W}^{\pm }$ Final States

Abstract

In the light of the most recent data from Higgs boson searches and analyses, we re-assess the scope of the Large Hadron Collider in accessing heavy charged Higgs boson signals in $b\bar{b}{W}^{\pm }$ final states, wherein the contributing channels can be $H^{+}\to t\bar{b}$, $h{W}^{\pm },H{W}^{\pm }$ and $A{W}^{\pm }$. We consider a 2-Higgs Doublet Model Type-II and we assume as production mode $bg\to t{H}^{-}$ + c.c., the dominant one over the range $M_{H^{\pm }}\ge 480$ GeV, as dictated by $b\to s{\hat{I}}^3$ constraints. Prospects of detection are found to be significant for various Run 2 energy and luminosity options.
