摘要：

Monojet and monophoton final states with large missing transverse energy (6) are important for dark matter (DM) searches at colliders. We present analytic expressions for the differential cross sections for the parton-level processes, q (q) over bar (qg) -> g(q) chi (chi) over bar and q (q) over bar -> gamma chi (chi) over bar. for a neutral DM particle with a magnetic dipole moment (MDM) or an electric dipole moment (EDM). We collectively call such DM candidates dipole moment dark matter (DMDM). We also provide monojet cross sections for scalar. vector and axial-vector interactions. We then use ATLAS/CMS monojet + is not an element of(T) data and CMS monophoton + is not an element of(T) data to constrain DMDM. We find that 7 TeV LHC bounds on the MDM DM-proton scattering cross section are about six orders of magnitude weaker than on the conventional spin-independent cross section. (C) 2012 Elsevier B.V.
