Dark matter searches at Colliders and synergies with other experiments

One overarching objective of science is to further our understanding of the universe, from its
early stages to its current state and future evolution. This depends on gaining insight on the
universe’s most macroscopic components, for example galaxies and stars, as well as describing its
smallest components, namely elementary particles and nuclei and their interactions. The apparent
excess of "dark matter" in the universe remains one of the outstanding questions in science. If
dark matter is a particle, then it can be produced and sought at the Large Hadron Collider,
complementing searches in other experiments. This seminar focuses on the searches for dark matter
at present and future colliders, with a special highlight on the searches that allow to probe dark
matter hypotheses that are complementary to other experiments.

It is clear that solving the dark matter puzzle requires combined expertise from the fields of
particle physics, astroparticle physics and nuclear physics. Pursuing common scientific drivers
such as dark matter also requires mastering challenges related to instrumentation, data
acquisition, selection and analysis, as well as making data and results available to the broader
science communities. This seminar also presents the work that various communities and experiments
are doing in this direction, and the ongoing initiatives aiming to exploit synergies across
different communities.
