Discovery Seminar - speaker Ning Zhou

Abstract: 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 sqrt(s)=8TeV using data recorded with the ATLAS detector at the LHC. Events with a hadronic jet with the jet-mass consistent with a W and Z boson, and with large missing transverse momentum are analyzed. The data are consistent with the SM expectations. Limits are set on the mass scale in effective field theories that describe the interaction of dark matter and SM particles, and the cross section of Higgs decay to invisible particles in a UV complete theory with the Higgs boson as a light mediator
