In this talk, I will briefly review our previous work on heavy neutrino and new Higgs searches. The search strategies are developed for sterile neutrinos at proton-proton colliders and for singly charged Higgs at electron-proton colliders. For heavy sterile neutrinos with masses below $M_W$, the trilepton plus missing energy final states are investigated to discover sterile neutrinos and to discriminate between Dirac and Majorana heavy neutrinos. When the masses of sterile neutrinos are above 200 GeV, we use the final state of lepton flavour violating (but lepton number conserving) dilepton dijet ($e^\pm \mu^\mp jj$) to search for sterile neutrinos in lowscale seesaw scenarios. For extra Higgs bosons, we search for the fiveplet singly charged Higgs $H^\pm$ in the Georgi-Machacek model at the ep colliders by exploiting the production of $p\, e^- \to j\, e^-\, H^\pm$ via the $ZW^{\pm}$ fusion process, and decay as $H^\pm \to Z\, W^{\pm} \to (l^+ l^-)\, (jj)$. For all analysis, the Multivariate Analysis (MVA) methods are performed to maximally reject the Standard Model (SM) background at the detector level and to enhance the discovering limits. |
