Description
Although measurements confirm the Standard Model of particle physics
(SM) to high precision until now, multiple shortcomings motivate the
search for physics beyond the SM. For example, the SM does not offer a
candidate particle to explain (cold) dark matter (DM). A comprehensive
search program is carried out by direct and indirect detection
experiments, but also at particle colliders like the Large Hadron
Collider (LHC) using proton-proton collisions.
As DM particles are not electromagnetically or strongly interacting,
they cannot directly be detected in the detectors at the LHC. Instead,
the presence of DM particles would lead to missing momentum in the
transverse plane to the proton-proton collision (ETmiss), which is thus
an important signature in these searches. DM particles could be produced
in proton-proton collisions directly through a mediator particle linking
SM particles to DM particles, or could be produced in the decay of other
new particles, like supersymmetric particles.
This talk presents recent highlights of these searches at the ATLAS
detector at the LHC, with major involvements of the LMU and MPP groups.
The results will be placed in context to (in)direct detection
experiments to discuss the complementarity of the different searches.
