Abstract

We investigate the possibility of the identification of TeV physics models including WIMP dark matter at the International Linear Collider. Many TeV physics models contain a WIMP dark matter (chi⁰) and charged new particle (chi^pm) which interacts with the WIMP dark matter via the vertex chi^pm chi⁰ W^mp. Through Monte Carlo simulations, we study the process, e⁺e^- to chi⁺ chi^- to chi⁰ chi⁰ W⁺ W^-, because the signal contains the fruitful information of the model. We show that, in particular, the distribution of the chi^pm production angle is the powerful probe in the TeV physics model search.
