On the trail of dark matter by use of simplified models at CMS — Michael Dürr, Alexander Grohsjean, Kai Schmidt-Hoberg, Christan Schwanenberger, and •Nicole Stefanov — DESY, Hamburg, Germany

Various astrophysical observations could consistently be explained by the existence of dark matter. Assuming that it is a so-called weakly interacting massive particle, it could be produced and observed at the Large Hadron Collider.

In this talk, by use of simplified models, such a search for dark matter produced in association with a dileptonically decaying top quark pair will be covered focusing on the challenging kinematic reconstruction of the final state containing undetectable neutrino and dark matter pairs. The kinematic reconstruction is of particular interest since it enhances the detection capability of a potential signal and - in case of a discovery - it allows to study the nature of DM in great detail. Moreover, discovery prospects for extensions of the usual simplified models will be discussed.
