Searching for the doubly-charged Higgs bosons in the Georgi-Machacek model at the electron-proton colliders

Abstract

The Georgi-Machacek model is one of many beyond Standard Model scenarios with an extended scalar sector which can group under the custodial $\mathrm{SU}(2{)}_{\mathrm{C}}$ symmetry. There are 5-plet, 3-plet and singlet Higgs bosons under the classification of such symmetry in addition to the Standard Model Higgs boson. In this paper, we study the prospects for detecting the doubly-charged Higgs boson (${\mathrm{H}}_5^{\pm \pm }$) through the vector boson fusion production at the electron-proton (ep) colliders. We concentrate on our analysis through $\mu$-lepton pair production via pair of same-sign W bosons decay. The ${\mathrm{H}}_5^{\pm \pm }$ discovery potentials at the ep colliders are presented.
