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

摘要

The Georgi-Machacek model is one of many beyond-Standard Model scenarios with an extended scalar sector that can group under the custodial SU(2)_C symmetry. There are 5-plet, triplet, 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 (H_5~(±±) ) through the vector boson fusion production at the electron-proton colliders. We concentrate on our analysis through μ-lepton pair production from a pair of same-sign W bosons decay. The H_5~(±±) discovery potentials at the electronproton colliders are presented.
