Dark Matter (DM) is a long standing puzzle in high energy physics and goal of a diverse research program. Recent tantalizing excesses in underground DM searches increase emphasis on the low masses region. At the LHC we have great sensitivity to this region and are able to test a phase space not accessible otherwise.

I am presenting first searches using events containing jets, photons and W-bosons to search for DM pair production. By utilizing an effective field approach we achieve complementary and comparable sensitivities to direct and indirect dark matter searches in regions where recent excesses have been reported. Furthermore new signatures involving heavy quarks (b-quarks or top-quarks), theoretical developments and comparisons to underground and indirect searches will be discussed.

This is the first systematic program to explore DM at low mass with high sensitivity at the LHC. A potential discovery of DM or the constraints achievable by this program will revolutionize our picture of particle physics and astrophysics.
