Description
We investigate ways of identifying two kinds of dark matter component particles at high-energy colliders. The strategy is to notice and
distinguish double-peaks(humps) in some final state observable. We
carried out our analysis in various popular event topologies for dark
matter search, such as mono-X and n-leptons+n-jets final state along
with missing energy/transverse momenta. It turns out that a lepton-collider is suitable for such analyses. The observables which are best-suited for this purpose have been identified, based on the event topology. The implication of beam-polarization is also explored in detail. Lastly, a quantitative measure of the distinguishability of the two peaks has been established in terms of a few newly-constructed interesting variables.
