Abstract:

A search is presented for production of dark-matter particles recoiling against a leptonically decaying Z boson in 20.3fb-1 of pp collisions at s=8TeV 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. © 2014 CERN, for the ATLAS Collaboration.

  • ATLAS uses a right-handed coordinate system with its origin at the nominal interaction point (IP) in the center of the detector and the (Equation presented) axis along the beam pipe. The (Equation presented) axis points from the IP to the center of the LHC ring, and the (Equation presented) axis points upward. Cylindrical coordinates (Equation presented) are used in the transverse plane, (Equation presented) being the azimuthal angle around the beam pipe. The pseudorapidity is defined in terms of the polar angle (Equation presented) as (Equation presented); (2012) Eur. Phys. J. C, 72, p. 1909. , ATLAS Collaboration,.
