A shot in the dark
The experiments at the Large Hadron Collider at CERN are at the energy frontier of particle physics, searching for answers to fundamental questions of nature. In particular, dark matter presents strong evidence for physics beyond the standard model. However, there is no experimental evidence of its non-gravitational interaction with standard model particles. If dark matter has non-gravitational interactions with the standard model particles, we could be producing the dark matter particles in the proton-proton collisions at the LHC. While the dark matter particles would not produce an observable signal in the detector, they may recoil with large transverse momentum against visible particles resulting in an overall transverse momentum imbalance in the collision event. In this talk, I will review the searches for dark matter particles in the missing momentum final states in association with jets at the Compact Muon Solenoid (CMS) experiment.
