A search is presented for dark matter pair production in association with a W or Z boson in pp√collisions representing 20.3 fb−1 of integrated luminosity at s = 8 TeV using data recorded with theATLAS detector at the Large Hadron Collider. Events with a hadronic jet with the jet mass consistentwith a W or Z boson, and with large missing transverse momentum are analyzed. The data areconsistent with the standard model expectations. Limits are set on the mass scale in effective fieldtheories that describe the interaction of dark matter and standard model particles, and on the crosssection of Higgs production and decay to invisible particles. In addition, cross section limits on theanomalous production of W or Z bosons with large missing transverse momentum are set in twofiducial regions.
