Observability of Inert Scalars at the LHC

Abstract

In this work we investigate the observability of Inert Doublet Model scalars at the LHC operating at the center of mass energy of 14 TeV. The signal production process is $pp\to A{H}^{\pm }\to ZH{W}^{\pm }H$ leading to two different final states of ${\ell }^{+}{\ell }^{-}HjjH$ and ${\ell }^{+}{\ell }^{-}H{\ell }^{\pm }\nu H$ based on the hadronic and leptonic decay channels of the W boson. All the relevant background processes are considered and an event selection is designed to distinguish the signal from the large Standard Model background. We found that signals of the selected search channels are well observable at the LHC with integrated luminosity of 300 fb${}^{-1}$.
