Light dark matter annihilation and scattering in LHC detectors

Bauer, Martin and Foldenauer, Patrick and Reimitz, Peter and Plehn, Tilman (2021) 'Light dark matter annihilation and scattering in LHC detectors.', SciPost physics., 10 (2). 030.


We systematically study models with light scalar and pseudoscalar dark matter candidates and their potential signals at the LHC. First, we derive cosmological bounds on models with the Standard Model Higgs mediator and with a new weak-scale mediator. Next, we study two processes inspired by the indirect and direct detection process topologies, now happening inside the LHC detectors. We find that LHC can observe very light dark matter over a huge mass range if it is produced in mediator decays and then scatters with the detector material to generate jets in the nuclear recoil.
