Mono-Z dark matter search with the ATLAS detector

Sumario:A search with ATLAS detector is presented for collider signatures of weakly interacting dark matter particles (WIMPs) leading to mono-Z signal. Events with large missing transverse momentum and two oppositely-charged electrons or muons consistent with the decay of a Z-boson were selected in analysis. The limits on the mass scale of the contact interaction as a function of the dark matter particle mass and the limits on the coupling and scalar particle mediator obtained from Run 1 ATLAS data are shown. Analysis techniques specific to Run 2 are reviewed.
