There exists a general model framework where dark matter can be a vanilla
WIMP-like thermal relic with a mass of ${\cal O}$(100 GeV), but it still
escapes direct detection. This happens, if the dark matter particle is a
Goldstone boson whose scattering with ordinary matter is suppressed at low
energy due to momentum-dependent interactions. We outline general features of
this type of models and analyse a simple realization of these dynamics as a
concrete example. In particular, we show that although direct detection of this
type of dark matter candidate is very challenging, the indirect detection can
already provide relevant constraints. Future projections of the
indirect-detection experiments allow for even more stringent exclusion limits
and can rule out models of this type.
