Abstract
AbstractWe analyze the signal sensitivity of multi-lepton final states at the collider that can arise from doubly and singly charged Higgs decay in a type-II seesaw framework. We assume triplet Vacuum Expectation Value (VEV) to be very small and degenerate masses for both the charged Higgs states. The leptonic branching ratio of doubly and singly charged Higgs states have a large dependency on the neutrino oscillation parameters, lightest neutrino mass scale, as well as on neutrino mass hierarchy. We explore this as well as the relation between the leptonic branching ratios of the singly and doubly charged Higgs states in detail. We evaluate the effect of these uncertainties on the production cross-section of multi-lepton signal. Finally, we present a detailed analysis of multi-lepton final states for a future hadron collider HE-LHC, that can plausibly operate with the center of mass energy \(\sqrt{s}=27\) TeV.KeywordsType-II seesaw mechanismCharged HiggsHE-LHC
