We discuss universal signals of consistent models of pseudoscalar mediators
for collider searches for Dark Matter. Keeping only the degrees of freedom that
can not be decoupled due to consistency conditions, we present a universality
class of simplified models with pseudoscalar mediators and renormalizable
couplings to Standard Model fields. We compute stability and perturbativity
constraints, constraints from electroweak precision measurements, collider
searches for new heavy particles as well as constraints from relic density
measurements and indirect detection experiments searching for signals of Dark
Matter annihilation into photons. We find that the mono-$Z$ final state is the
strongest, universal signal of this class of models, with additional signatures
present in the different ultraviolet completions that can be used to
distinguish between them.
