Description
The Dark Matter (DM) nature remains one of the great puzzles of particle
physics; while we know that about 27% of the universe is in the form of
DM, little is known about its properties. If produced at the LHC, it should couple to the standard model though some mediator. The mediator can decay into dark
matter particles that escape the detector, leaving a large missing transverse
momentum (MET) as their signature. Also the mediator can decay into two quarks, which would appear as a bump in the invariant dijet mass spectrum. Recent results from ATLAS based on the presence of significant MET along with a variety of objects, and a dijet mass-spectrum analysis will be discussed.
