Identification of new physics and general WIMP search at the ILC
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 (chipm) which interacts with the WIMP dark matter via the vertex chipm chi0 Wmp. 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 chipm production angle is the powerful probe in the TeV physics model search.
