  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.
