Limits on electrophilic Dark Matter from LHC Monojets

Abstract

Searches for WIMP Dark Matter particle at the LHC are considered from the point of view of the existence of a Dark Matter particle which couples primarily through the heavy gauge boson Z, as suggested by recent tentative evidence for a 130 GeV gamma line in the FermiLAT data. We compare three models in which the WIMP is a neutrino-like particle and consider the limits on such particle and interactions from LHC.
