Same-sign Charged Higgs Pair Production in bosonic decay channels at the HL-LHC and HE-LHC

Abstract

Same-sign charged Higgs pair production via vector-boson scattering is a useful probe of the mass spectrum among the heavier scalar, pseudoscalar, and charged Higgs bosons in two-Higgs-doublet models. It has been shown that the production cross section scales as the square of the mass difference $\Delta m=(m_{H^0}-m_{A^0})$ in the alignment limit $(\cos (\beta -\alpha )=0)$. We study the potential measurement of this same-sign charged Higgs pair production at the high-luminosity LHC (HL-LHC) and the proposed 27 TeV $pp$ collider, with emphasis in the decay channel $H^{\pm }{H}^{\pm }\to (W^{\pm }{A}^0)(W^{\pm }{A}^0)$, which is in general the dominant mode when the charged Higgs mass is above the $W^{\pm }{A}^0$ threshold. We also examine the current allowed parameter space taking into account the theoretical constraints on the model, the electroweak precision measurements, $B$ decays, and direct searches in the $H^{\pm }\to {\tau }^{\pm }{\nu }_{\tau }$ and $H^{\pm }\to W^{\pm }{A}^0\to ({\ell }^{\pm }{\nu }_{\ell })(\mu \mu )$.
