  This Report provides an extensive review of the experimental programme of
direct detection searches of particle dark matter. It focuses mostly on
European efforts, both current and planned, but does it within a broader
context of a worldwide activity in the field. It aims at identifying the
virtues, opportunities and challenges associated with the different
experimental approaches and search techniques. It presents scientific and
technological synergies, both existing and emerging, with some other areas of
particle physics, notably collider and neutrino programmes, and beyond. It
addresses the issue of infrastructure in light of the growing needs and
challenges of the different experimental searches. Finally, the Report makes a
number of recommendations from the perspective of a long-term future of the
field. They are introduced, along with some justification, in the opening
Overview and Recommendations section and are next summarised at the end of the
Report. Overall, we recommend that the direct search for dark matter particle
interactions with a detector target should be given top priority in
astroparticle physics, and in all particle physics, and beyond, as a positive
measurement will provide the most unambiguous confirmation of the particle
nature of dark matter in the Universe.
