Abstract :We investigate the process e^+ e^-⟶H^+ H^- in the framework of the scotogenic model. The process receives different contributions arising from tree-level diagrams mediated by photon exchange, Z boson exchange and from the exchange of new singlet right-handed fermions N_1,2,3. We estimate the size of each contribution and the total cross section of the process after applying all dominant constraints on the parameters of the model. We show that the dominant contribution to the cross section originate from the new singlet right-handed fermions N_1,2,3. Additionally, we show the dependency of the cross section on the centre of mass energy for set of benchmark points of the parameter space of the model respecting the strong obtained bounds. These predictions can be tested in future e^+ e^- colliders and hence can test the validity of the model or setting further strong constraints on the model.
