The origin of dark matter is one of the most important and challenging questions in high energy physics today. A search for dark matter is performed in the data collected by the CMS experiment in run I and run II. In this search, the dark matter particle recoils against a leptonically decaying W or Z boson, leading to the distinct signatures of either one or two isolated leptons and missing transverse energy. Both channels allow to study various specific features of dark matter production. Different aspects of the background determination and its systematic uncertainties are presented. Dark matter production can be described either by an effective field approach or by fully describing the mediator with a simplified model. Both options will be discussed.
