  Physics Beyond Colliders is an exploratory study aimed at exploiting the full
scientific potential of CERN's accelerator complex and its scientific
infrastructure in the next two decades through projects complementary to the
LHC, HL-LHC and other possible future colliders. These projects should target
fundamental physics questions that are similar in spirit to those addressed by
high-energy colliders, but that require different types of beams and
experiments. A kick-off workshop held in September 2016 identified a number of
areas of interest and working groups have been set-up to study and develop
these directions. All projects currently under consideration are presented
including physics motivation, a brief outline of the experimental set-up and
the status of the corresponding beam and detector technological studies. The
proposals are also put in context of the worldwide landscape and their
implementation issues are discussed.
