Search for dark matter in events with a Z boson and missing transverse momentum in pp collisions at √s =8TeV with the ATLAS detector

A search is presented for production of dark-matter particles recoiling against a leptonically decaying Z boson in 20.3 fb<SUP>-1</SUP> of <i>pp</i> collisions at √s=8 TeV with the ATLAS detector at the Large Hadron Collider. Events with large missing transverse momentum and...

description	A search is presented for production of dark-matter particles recoiling against a leptonically decaying Z boson in 20.3 fb<SUP>-1</SUP> of <i>pp</i> collisions at √s=8 TeV with the ATLAS detector at the Large Hadron Collider. Events with large missing transverse momentum and two oppositely charged electrons or muons consistent with the decay of a Z boson are analyzed. No excess above the Standard Model prediction is observed. Limits are set on the mass scale of the contact interaction as a function of the dark-matter particle mass using an effective field theory description of the interaction of dark matter with quarks or with Z bosons. Limits are also set on the coupling and mediator mass of a model in which the interaction is mediated by a scalar particle.
