  This document is the final report of the ATLAS-CMS Dark Matter Forum, a forum
organized by the ATLAS and CMS collaborations with the participation of experts
on theories of Dark Matter, to select a minimal basis set of dark matter
simplified models that should support the design of the early LHC Run-2
searches. A prioritized, compact set of benchmark models is proposed,
accompanied by studies of the parameter space of these models and a repository
of generator implementations. This report also addresses how to apply the
Effective Field Theory formalism for collider searches and present the results
of such interpretations.
