Description
We investigate the discovery prospect of doubly-charged Higgs boson at future electron collider Compact Linear Collider (CLIC). After neutrino mass generation through the Type II seesaw mechanism, we examine the small vacuum expectation value (VEV) parameter region of the type-II seesaw model in four different collision modes. In this region, $\mathcal{O}(1)$ Yukawa couplings between Higgs triple and charged leptons are expected, leading to a substantial cross section at linear colliders. Our results demonstrate that a doubly-charged Higgs boson with a mass around one TeV can be observed at the $5\sigma$ confidence level, assuming an integrated luminosity of $300~{\rm fb}^{-1}$.
