Abstract
We investigate the phenomenology of the light charged and neutral scalars in Inert Doublet Model at future e + e − colliders with center of mass energies of 0.5 and 1 TeV, and integrated luminosity of 500 fb−1. The analysis covers two production processes, e + e − → H + H − and e + e − → AH, and consists of signal selections, cross section determinations as well as dark matter mass measurements. Several benchmark points are studied with focus on H ± → W ± H and A → ZH decays. It is concluded that the signal will be well observable in different final states allowing for mass determination of all new scalars with statistical precision of the order of few hundred MeV.
